Well, I don't know about mandrake, but most other linux distributions
are binary compatible within when you make minor upgrades (8.0 to 8.1) but
major version changes (7.2 to 8.0) usually breaks at least some of the
binary compatibility. So, I'm not surprised it broke when you upgraded the
system, but I don't know why a recompile didn't help :-)
Apart from the standard system libraries (libc, libm, libnsl, all the X
we only need fftw, and lam if you want to run in parallel. Mandrake might
come with its own version of fftw that probably works, but again it might not
that's why we recommend to use the version we have on our homepage. Or
compile it from source - it's straighforward.
I guess the update program should bring your installation more or less in
with a fresh 8.0 install, so unless you have made any major changes to the
installation this sounds like a bug in the Mandrake updater?
You could try to turn off all features in the configure script to see if that
but I doubt it will since everything works on the fresh 8.0 install. :-/
