version `GCC_3.3' not found

   I am trying to run InsightII 2000.3L from Accelrys on a Fedora Core 4
x86_64 box in linux32 mode. The software is having problems loading
with the error...

/usr/accelrys/I2000.3L/Linux_2_Intel_32/biosym_exe/insightII: /usr/accelrys/I2000.3L/Linux_2_Intel_32/biosymso/libgcc_s.so.1: version `GCC_3.3' not found (required by /usr/lib/libstdc++.so.6)

This software was built against RHEL 2 and is patched to be compatible with
RHEL 3. Their newer software built specifically to be compatible with
RHEL 3 doesn't show this error. Any ideas on how to work around this?
