I came across this bug on Usenet in Message-ID: <2mmrh4Fop53qU1@uni-berlin.de>.
Basically, gcc needs to be compiled with the f77 USE flag in order to build g77.
However, no check is done and non-developers wouldn't know what to do with the error message.
The Bash built-in 'type' function can be used to find out if g77 exists on the system, and fail the build with a more useful error message.
I'll attach a solution that works for me.
