Comment(by Valene):

 I already tried to put an alias, but it didn't work.
 I also tried to hack g95.py and change g95 commands by ftn. I obtained the
 same error.
 The thing is that scipy compiles with the good compiler before.
 You can see that in the scipy_log :

 That's why I don't understand why, for this extension, scipy doesn't find
 any compiler.

 Adding a new compiler should result to the same problem than in
 http://projects.scipy.org/scipy/ticket/886 ticket.

 Someone has an idea why it finds fortran compilers before and then not ?

 Thank you
