>Description:
math/py-numpy currently does not build for me on Solaris 10 using lang/gcc34:

building library "npymath" sources
customize GnuFCompiler
Could not locate executable f77
Could not locate executable g77
Traceback (most recent call last):
  File "setup.py", line 187, in <module>
    setup_package()

This used to work a few weeks ago, probably after the last change to 
math/py-numpy itself. I still use Python 2.6 and haven't switched to 2.7 yet, 
if that's of interest.

I have checked PRs 44130, 40663 and 44626, but they didn't give me any ideas 
how to fix this problem. f2c is installed, btw.
