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