Update for osx 10.9

Dear Valentin,

the script to install cmssh does not cover the newest Mac os version 10.9.
There are so far no CMSSW releases compiled for this version, but the 10.8 might be compatible with it.
It would be enough to change the line if osx_ver() == '10.8': to if osx_ver() == '10.8' or osx_ver() == '10.9': in the cmssh_install.py script.

After this, I manage to install and start cmssh, though I still get an error which ends with:
---> 21 from matplotlib.backends import _macosx
22
23

ImportError: dlopen(/Users/demattia/CMSSH/soft/install/lib/python2.7/site-packages/matplotlib/backends/_macosx.so, 2): Symbol not found: _sqlite3_intarray_bind

_warn("Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.", PowmInsecureWarning)

Do you know what might be wrong and how I could fix it?

Many thanks for any help,

Marco
