[MITgcm-support] MITgcm on snow leopard

[Yuan Lian]

Yes download the gcc 4.6 (gcc and gfortran for snow leopard) from 
http://hpc.sourceforge.net/, then
extract the packages. Do "sudo cp -r ~/Downloads/usr /" (assuming you 
extract the packages
in Downloads folder". This will update the gfortran to latest version. 
gcc will still be default one
from Xcode 3.2 but you can force the compiler to use the experimental 
one. In my case I used
/usr/bin/gcc, it will work just fine.
