Octave without the GUI is definitely doable today on RHEL 5, I've been
running it regularly. I think all the dependencies are there, the only
system libraries that I have had to replace are BLAS and LAPACK (and
ATLAS optionally) because of a bug in the way they were compiled for
RHEL 5 (https://bugzilla.redhat.com/show_bug.cgi?id=557977)

With the GUI would need a version of Qt (4.6 or 4.8) and Qscintilla
built for RHEL 5. I tried backporting Qt 4.6 the other day and ran
into some errors, didn't look into it too deeply yet.
