Re: libgmp issue with StarCluster 0.9.3 on Ubuntu 10.04

My bad, I didn't read your message closely enough - you claimed to have
already installed libgmp. How did you install libgmp 5.0.2? Manually
from source, or from some deb package you downloaded?

Most likely reinstalling StarCluster did not trigger a rebuild of
pycrypto. Try manually deleting pycrypto from your site-packages
directory and then reinstall StarCluster.

If that still doesn't fix things then pycrypto is likely not detecting
your new libgmp install in which case you should probably post a
question to their mailing list[1] with details about how you installed
libgmp and the build output when running 'python setup.py install' from
pycrypto's source directory.

HTH,
