have you any clue on how to fix it ?

i used "setup.py build" as build system
trying with scons i received the same error.


i used this instruction :

# clone scipy from git repository
# cd into scipy

export CC=gcc-4.2
export CXX=g++-4.2
export FFLAGS=-ff2c

python setup.py build



dyn-128-128-201-211:scipy epifanio$ which gfortran
/usr/bin/gfortran

Many thanks for any help!
