F2c
From charlesreid1
f2c (fortran-2-c) is a library which allows the conversion of Fortran code into C code. It comes in really handy if you're not a Fortran person and you're given a Fortran code to deal with.

# 2. Eliminate all references to the math library (-lm) in #
# the script 'fc' since it is included the System framework #
# and is linked by default under Mac OS X. #
# 3. Eliminate '-u MAIN__' at the bottom of the 'fc' script. #
# You will have to explitly load FORTRAN MAIN programs #
# (explicitly mention the relevant .f or .o file). #

Copy and paste this into a script file, say, build.sh. Then make the build script executable:
$ chmod +x build.sh
and run the build script (you have to be the superuser, or else you have to go through the script and replace all the /bin and /usr/bin stuff with your own directories - if you do that, don't forget to add the location to your path!)
Finally, to ensure you've installed it OK, type:
$ which f2c
and it should tell you where it's at.
