LAPACK testing

How to build Lapack test routines for AMD x86_64 running Gentoo?

Please help!
I am trying to run the test routines for the Lapack and BLAS
libraries to make sure the libraries are installed correctly
before I port my code from 32 to 64-bits. I downloaded and
unpacked the tarballs from (just for the test routines).
I edited the to use the gcc compiler and point at my
acml blas and lapack libraries. The pertinent lines from my file are as follows:

FORTRAN = gfortran
OPTS = -march=k8 -funroll-all-loops -O3
NOOPT = -march=k8
LOADER = gfortran
BLASLIB = `pkg-config --libs blas`
LAPACKLIB = `pkg-config --libs lapack`
TMGLIB = tmglib$(PLAT).a
EIGSRCLIB = eigsrc$(PLAT).a
LINSRCLIB = linsrc$(PLAT).a

To test, I am using the command: make lapack_testing

I originally suspected my problems were with my compiler flags,
although I am beginning to wonder if this isn't another 32/64-bit
conversion problem since with these flags, I get an error when I
run the executables. The executables are not able to read the
input files correctly. Instead, the output indicates it could not
recognize the input. For example:

SEQ: Unrecognized path name

Any help, guidance, advice, ..., would be greatly appreciated! (And
to make sure I haven't left anything out, below is some information
on my machine architecure and Gentoo installaton.) Thanks in advance...
