Hello,

I've installed scipy and numpy from Andrew Straw's repository, all other
libraries are from the standard Ubuntu repositories (6.10).  When I
execute scipy.test(), the following warnings appear:

****************************************************************
WARNING: clapack module is empty
-----------
See scipy/INSTALL.txt for troubleshooting.
Notes:
* If atlas library is not found by numpy/distutils/system_info.py,
  then scipy uses flapack instead of clapack.
****************************************************************

****************************************************************
WARNING: cblas module is empty
-----------
See scipy/INSTALL.txt for troubleshooting.
Notes:
* If atlas library is not found by numpy/distutils/system_info.py,
  then scipy uses fblas instead of cblas.
****************************************************************

Running the command:
ldd /usr/lib/python2.4/site-packages/numpy/linalg/lapack_lite.so

Gives me:
        linux-gate.so.1 =>  (0xffffe000)
        liblapack.so.3 => /usr/lib/atlas/sse2/liblapack.so.3
(0xb7958000)
        libblas.so.3 => /usr/lib/atlas/sse2/libblas.so.3 (0xb7387000)
        libg2c.so.0 => /usr/lib/libg2c.so.0 (0xb735f000)
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7339000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb732e000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb71fa000)
        /lib/ld-linux.so.2 (0x80000000)

Is there a problem with the libraries I have installed?  Should I be
worried about these warnings, or am I just being compulsive?

Thanks for your help,
Jason
