[Lapack] Hi, Dear LAPACK Team

Hi, Dear LAPACK Team,

    Excuse me, I'm from  ShenZhen.China(Mainland), and I've download
CLAPACK3.2.1 package from to my home PC (Debian in
Chinese[simplified]) for my personal interest ,  and read the
readme.installed and tried to install clapck , but I met trouble.

    First, I used ATLAS3.9.32 (from to generate a tuned
optimized BLAS, and I tested atlas library(libcblas.a, libf77blas.a,
libatlas.a) successly in ATLAS test procedure. But when I set by
"BLASLIB = -lf77blas -latlas -lgfortran" and "CC = gcc-4.5 -DNO_BLAS_WRAP",
I got a error message in blas_testing as "???" in Chinese (it means
"segmentation fault") in ./xblat1c and ./xblat1z run time.

    Then, (after make cleanall) I reset by "CC = gcc-4.5", and
"BLASLIB = ../../libfblaswr.a -lf77blas -latlas -lgfortran" , but there is
still error messages as "???" (segmentation fault).

    So, I reset by "CC = gcc-4.5 -DNO_BLAS_WRAP" and "BLASLIB =
../../blas$(PLAT).a", and I built blas library within clapack. There was no
any error message in link and run time, but I checked the blas testing
result(c/d/s/z-blat-1/2/3.out) and found there were some "FATAL ERROR"s in
these .out file (espetially in sblat*.out, single precision complex number).
I've send these .out file to you within patch (tar.gz format).

    Some of my friends have install clapack successly with optimized BLAS
(ATLAS, ACML,etc) in different system (Ubuntu, Fedora, Debian), and now they
are successful and enjoying this matrix library. But I, (set my as
same as theirs) failed again and again. I know I must miss something , but I
don't know what it exactly is.

   Would you mind to tell me some advices or check my makefile and test
result ? Or my compiler environment and configuration has some bugs?
