Hm, I'm still having problems with this,

I added these lines (at line 14126) to the configure script:

echo  "`ls -l ./conftest.$ac_ext`"
echo  "`cat ./conftest.$ac_ext`"
echo  "`ls -l  ./conftest$ac_exeext`"
echo  "`./conftest$ac_exeext`"

and the configure output was:

So the fortran test file seems OK but ./conftest don't print anything (it should be 'succeeded'
or 'failed', right?). Too verify that there is no problem with the BLAS lib I did this in matlab,

>> zx = 1:10 + i*zeros(1,10);

>> zy*zx'

ans =

which uses the same BLAS and LAPACK libs, which is set by these exports:

export BLAS_VERSION=/usr/local/lib/libBLAS.so
export LAPACK_VERSION=/usr/local/lib/libLAPACK.so
export LAPACK_VERBOSITY=1
export MATLAB_MEM_MGR=system
