Note that Mathematica <= 4.0 is compiled with libc5 and Red Hat >= 5.x
uses glibc6.  I get crashes when mixing them.  You might want to try
my gcc-libc5 rpm available from

 ftp://robotics.caltech.edu/pub/radford/

It should not interfere with the normal operation of your system.
Almost everything it installs goes in /usr/i486-linux-libc5.

You then need to prefix the "mcc" command with

  CC="gcc-libc5 -Wl,-rpath -Wl,/usr/i486-linux-libc5/lib"
