Are there any well-know conflicts between octave 2.0.14 and standard
Red Hat linux configurations?

I did a standard RH6.1 install on my laptop (thinkpad 560X), and
recently I installed the octave rpm, but I get a segfault error
immediately upon typing 'octave' -- if I'm missing something obvious
I'd be delighted if something pointed it out.

I both used the standard rpm, and compiled from the source rpm, each
time with the same results.

Thanks,

Here are the appropriate libraries:
