This is the important error in the configure result -- according to the
"nm" output below, this check should have succeeded instead:

>> nm ~/pacakages/mkl/lib/32/libmkl_ia32.a | grep sgemm_
> ...

Can you open the file "config.log" that was created during configure,
and look for the exact (compiler/linker) error message on the failed
test? To find this place, search for the string "checking for sgemm_" in
that file. Maybe the compiler doesn't like the tilde ("~"), in which
case you should specify a complete absolute path name instead.

Regards,

Christian
