It seems to be the reason, I just did a quick check on my system:

gromit:/usr/src/SpecTests/cpu2000/benchspec/CFP2000/168.wupwise/run/00000001:[0]
$ ldd ./wupwise
        libg2c.so.0 => not found
        libm.so.6 => /lib/libm.so.6 (0x4002d000)
        libgcc_s.so.1 => /opt/gcc-3.1-devel/lib/libgcc_s.so.1 (0x40050000)
        libc.so.6 => /lib/libc.so.6 (0x40059000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Thanks Toon for the analysis!
