gotta love g++. In Performer 2.4, we encountered a similar error so we
statically linked against:
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/libgcc.a
which contains that symbol. We got this when we added support for the
Pentium's time stamp counter which is 64bits. The Cycle-Counter we use
under IRIX is 32bits. When we changed all the appropriate data-types to
use the full 64bits, g++ decided to use a different compare function
(__ucmpdi2) (grrr). Link against that libgcc.a and that should fix your
problem.

hope that helps,
tom
