I've read stuff saying /opt and /usr/local are practically the same but I would
definitely follow the Debian Policy Manual and put it under /opt (since I didn't
find anything against that -- it is an add-on package).

Here's how I would do it:
Create an install directory /opt/euphoria/[ver]/* (regular Euphoria hierarchy).
As with any other package, the user can override this.

Modify the interpreter source so if EUDIR and EUINC do not exist, then look in
/etc/euphoria.conf (or something) for the proper values and set them. The
installation scripts should create this file. A person will be able to override
these in his or her own startup files, though.

Create a soft link /usr/bin/exu that points to the exu binary.

Where do other languages like Python and Perl put their hierarchies? I'll have
to peek into one of their files.
