I don't have "python" installed (but "python2").
I encountered this bug when I compiled frpg fist time on my new software setup.
I can reproduce it removing all code files from the repo and doing "git reset
--hard HEAD" afterwards.

configure log is attached

when I compile, the process stops with

Probably we should add python to the configure script?
