[SciPy-user] 'from scipy import linalg' fails

Good morning,

 I installed scipy 0.7.0 and numpy 1.3.0 on 64bit RedHat Linux 3 ES
(kernel 2.4.21-37.Elsmp, AMD-based hardware) 

 Since there was a known bug for incomplete blas packags on RedHat, I
properly compiled lapack 3.1.1 and atlas 3.8.3 and installed the
resultant  files in /usr/local/lib/atlas dir. I set up an env var
ATLAS=/usr/local/lib/atlas/lib prior to scipy build/install process.

 Here is an error message I get:

 % python2.5
 >>> from scipy import linalg;
 Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "/usr/local/python2.5/lib/python2.5/site-
 packages/scipy/linalg/__init__.py", line 8, in <module> from basic
import

    File

, line 389, in <module> import decomp
    File

    File
"/usr/local/python2.5/lib/python2.5/site-packages/scipy/linalg/blas.py",
line 14, in <module> from scipy.linalg  import fblas
 ImportError:
/usr/local/python2.5/lib/python2.5/site-packages/scipy/linalg/fblas.so:
undefined symbol: srotmg_


 I would appreciate your advice on how to address this issue.

 Thank you,

 Igor Klubok
