>Description:
Installing numpy depends on lang/g95 (g95-0.93nb7) as a dependency. However, building it on Linux blows up spectacularly as soon as it tries to compile the CRT:

And many more screenfuls of crap.


>How-To-Repeat:
cd lang/g95
bmake package-install
>Fix:
Should this be using gfortran instead of some ancient thing? Maybe gcc 4.1 is a little too old for the includes on this system.
