Look, it's difficult o understand what the actual problem is not seeing
the failing command line.

You might need to set LD_LIBRARY_PATH - my AppsFromScratch is doing this
because I was burned more than once not doing it.

Again, I suggest I'll send you my AppsFromScratch, if we are lucky, you'll
build 'octave' using just one command line, though it'll take a number of
hours.

I did this on 64 bit RHEL4, and I'm doing it regularly on 32 bit SUSEs
(10.2, 10.3), so, I guess, our chances are pretty good.

I wrote the tool because I didn't want to set all those environment
variables and type in all those 'configure', 'make', 'make install'
manually.

If you have problems, I'll most likely will be able to help you.

  Sergei.
