This part "-lmkl_gf_lp64.so -lmkl_gnu_thread.so -lmkl_core.so" looks wrong - it should be "-lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core" without the ".so" part.
I don't know how BLAS_LIBS does it, but when I was linking against mkl 9, all I did which different from the usual build (diff from the two rpm spec file I wrote) was 3 changes: export LDFLAGS=... -L/opt/intel/mkl/9.1/lib/em64t/ export FFLAGS=... -ff2c ./configure ... --with-blas="-lmkl -lguide -lpthread" The FFLAGS ezport was needed because of difference between g77 and gfortran.
