Could you please post the output.  It might help me understand and make
it work better.  Specifically, try:

$ wx-config --list

and

$ wx-config --libs

One thing I note is the wxWCharBuffer.  It looks like it's a unicode 
version of wxWidgets, which kinda makes sense, except that wxEuphoria doesn't
use unicode.  Based on that, I suspect that the names of the shared
libraries are different, so that there's not any conflict.  I'll have to
look into this, to see how difficult it will be to build everything with
unicode, which should make it compatible with the distro default.

Yeah, although I think it's pretty obvious now that it's the unicode thing
that's the real problem.  I do have a solution in the pipeline that I think
will work for just about everyone.  I'm looking into making a build of
euphoria (interpreter and translator + runtime) that statically links
with wxWidgets/wxEuphoria.  It'd make for a monstrous executable (3-7MB),
but it would contain all of the wxWidgets stuff, so that the external
dependencies would be minimized, to basically libc++ and gtk2. 

I've got a ways to go before there's something useful, and I'm right in the
middle of moving and being very busy at work...
