I can confirm that *this* was the problem on getting the correct ATLAS

Without stripping libraries:

$ gcc  xprint_buildinfo.c -o xprint_buildinfo -L $ATLAS -latlas
[alted at api alted]$ ./xprint_buildinfo
ATLAS version 3.6.0 built by alted on vie oct 15 17:02:42 CEST 2004:
   UNAME    : Linux api.uji.es 2.4.21-20.ELsmp #1 SMP Wed Aug 18 20:46:40 EDT 2004 i686 i686 i386 GNU/Linux

   MCCFLAGS : -fomit-frame-pointer -O

Stripping the libraries:

$ strip ATLAS/lib/Linux_P4SSE2_2/*.a
$ gcc  xprint_buildinfo.c -o xprint_buildinfo -L ATLAS/lib/Linux_P4SSE2_2 -latlas
/tmp/ccyNzrVf.o(.text+0x11): In function `main':
: undefined reference to `ATL_buildinfo'
collect2: ld returned 1 exit status

So, I removed scipy from python repository, deleted scipy source dir,
unpacked it again, recompiled it *against* the new, corrected ATLAS libs,
and... the same problem remains. However, now the number of tests are 600
instead of 574 with the stripped libs. The number of failed tests are 15 as

I'm attaching the complete output of 

$ python scipy_core/scipy_distutils/system_info.py


One of the error looks like:
