efc? AFAIK the official driver name for intel fortran is ifort, and this is
indeed on my path. An older name is ifc, though it complains about that command
name being deprecated:

brick at genugtig:/usr/local/src/numpy-0.9.6
$ ifc
ifc: warning: The Intel Fortran driver is now named ifort.  You can suppress
this message with '-quiet'
ifort: Command line error: no files specified; for help type "ifort -help"

brick at genugtig:/usr/local/src/numpy-0.9.6
$ efc
bash: efc: command not found

brick at genugtig:/usr/local/src/numpy-0.9.6
$ ifort -v
Version 9.0

brick at genugtig:/usr/local/src/numpy-0.9.6

I also added symbolic links for efc and efort. Still no-go though.

How can I obtain this test string? It did work with the older version
of scipy/f2py, so this may be some sort of regression.
