Well, programs compiled with gcc 3.x need a runtime library called libgcc_s.
This one cannot be found in your linker's search path.

Your options are:

- set LD_LIBRARY_PATH to the directory this library can be found (I think it
  will be in $GCC3_ROOT/lib)

- use the runtime_library_dirs of your setup.py to add the "-R" option to gcc.
  This should work, but in reality, it doesn't <wink>. It's either a bug in
  distutils or in my gcc (2.95.3).

- Add the $GCC3_ROOT/lib directory to your dynamic loader's search path
  (/etc/ld.so.conf)
