  One thing (not particularly related to Chimera) that is preventing us 
to upgrade the system, is the risk of breaking other programs. In a 
particular the newer versions of Linux come without G77 (Fortran 77 
compiler) and come with the newer "better" G90 compiler. I suspect a big 
headache when trying to compile old Fortran coded programs that we still 
use.
