the only clue I got is from a bug report googling the error string you
reported ("ValueError: A valid Fortran version was not found in this


that explains that the issue is related to the reporter using xsh and
suggests to use the command "unset SHELL" before building numpy, but
I'm not sure if it's related to your case.

besides this I really have no idea and I have no other suggestions,
sorry: you just have the ability to report errors that I cannot
reproduce at all so I cannot be much of help...
