Re: libgmp issue with StarCluster 0.9.3 on Ubuntu 10.04

This warning comes from PyCrypto and the fix is to install libgmp 5.x
and then reinstall pycrypto.

Unfortunately it looks like in Ubuntu 10.04 (Lucid) the libgmp version
is 4.3.2. You could either try installing libgmp 5.x manually either by
building from source or downloading a deb from some where or you might
consider upgrading to Ubuntu 11.10 (Oneiric) which has libgmp 5.x. It
*might* be possible to simply download the latest libgmp debs from
Oneiric and install using dpkg....

HTH,
