When I replace wxeu.so with Mario's version, I get:

  The wxEuphoria library "/home/rob/euphoria/bin/wxeu.so" could not be opened

both from translate/compiled and interpreted programs.

I have gcc version 3.3.2

With the original wxeu.so, I can run the demos with exu, but
not translated/compiled.

Thanks for the feedback on my compiled SO File.  Kennith, I'm glad you got it
working on your box.  And your problems with making it work on your box Robert.

It brings up several intresting questions that I'm feeling compelled to ask. If
both of you could answer these questions, it'd help me out in figuring out why
my version is working for Kennith, and not Robert, and why Matt's version is
causing errors on all three of our systems.

So here comes the questions:

What Linux Distrobution are you using? (I know, Ken is using Mandrake 10.1)
What Versions of GTK do you have installed on your computer? 1.2.x,
2.0.x, or both?
Where does your distro have GTK Installed to, or did you self-install/compile
it yourself to it's default location?

Somehow, I think one of the reasons why my version is failing to open on
Rob's computer, is possibly due to where GTK is installed to, but I need
to be sure, and these questions will help me out.

Apparently I have GTK and also GTK 2.0
I have Mandrake 10.0, and I'm using KDE 3.2 and gcc 3.3.2

I have that and I also have /usr/lib/gtk and /usr/lib/gtk-2.0 
I didn't compile anything myself.

I also double-checked the permissions on my euphoria/bin/wxeu.so
They are rwx rwx rwx, i.e. all permissions are "on", so it
would seem that something is failing when the .so is initialized.

Actually, the permissions aren't as strict as you would think, you only
need read permission on the user, and it will work just fine.

That is the correct size, so no corruption has occured.  If you could
Rob, try the following example, to ensure that it's attempting to load
the library, or not:

include dll.e

constant wxeu = open_dll("/home/rob/euphoria/bin/wxeu.so")
? wxeu

Be sure that the path is absolute, and leads to where wxeu.so is actually
stored on your box.  I just need to confirm that wxeu.so is not being
loaded at all.  wxEuphoria.e loads it through several methods, the main,
default one, is through grabbing the EUDIR Enviroment Variable, and
prepending it to /bin/wxeu.so.

Also, you can run a md5 checksum on the wxeu.so file, it should be
'537358fe225fb9488061102b635161fc'
You can run it through the following command "openssl dgst -md5 wxeu.so" if
you have OpenSSL installed on your Linux box.

Let me know of your results Rob, cause I'm still trying to work out some
details, and I want to eliminate any possibility of corruption if possible.

Okay, this brings up several intresting things that have come to my attention,
and need to ask a few more questions of Ken, Rob, and Matt.

What I basically need to know, is:

What Host system type do you have?  EG: i386-pc-linux-gnu, i486-pc-linux-gnu,
i686-pc-linux-gnu, etc, etc

Do you have the following libraries installed on your system:
  jpeg reader/decoder
  png reader/decoder
  regex system
  tiff reader/decoder
  zlib compression library

I'm starting to make progress, and if my assumptions are correct, I might
know of two things that may be causing failures on both Matt's system, and
Rob's system, while it works on my system, and Ken's system.

Actually, with a compiler, and the CPU, it does matter, cause certian
functions that can be optimized for certian CPU's, it will be, and it'll
cause the library not load on older CPUs.  Same applies for Executables.

I don't know what configure options Matt is using for his compile of
wxeu.so, so I'm using the default ones.

Yes, this I am doing as we speak, it's ./configure --enable-debug_dbg, which
as soon as I confirm that it's compiled properly, I'll upload it for both you
and Ken to run through GDB, to see if we might figure out what is happening.

I suggest that Matt does the same with his compile, so that we may get a
better idea of where it's crashing, with his compile.  If we can keep to 1
compile, it'll be easier to maintain, instead of multiple compiles.  But
if it comes to needing multiple compiles, Matt has allready said that he 
would be willing to do that.
