Hello,

After a comparatively uneventful, though long (4 hours to build ATLAS on
a 1.1 GHz Celeron), build from LAPACK and ATLAS tar-files and scipy CVS
(Nov 12 update), I got the following message when I tried to import
scipy:

Python 2.2 (#1, Apr 12 2002, 15:29:57) 
[GCC 2.96 20000731 (Red Hat Linux 7.2 2.96-109)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy
exceptions.ImportError: liblapack.so.3: cannot open shared object file:

    import calc_lwork

Would appreciate suggestions on how to fix this.  Build details and some
output are given below.

Thanks,

Ray

1) Build followed the INSTALL.txt in scipy CVS.  lapack.tgz and
atlas3.4.1.tar.gz were used.
