[Numpy-discussion] Installing numpy/scipy on CentOS 4

Robert,
	I looked in the build directory from Atlas and it is indeed 
generating the additional libraries. I copied them over to /usr/lib 
and rebuilt the numpy RPM. Indeed the behavior is different, and 
numpy sees the libraries. Of course some new oddities have entered 
the equation. Specifically this :

*********************************************************************
     Lapack library (from ATLAS) is probably incomplete:
       size of /usr/lib/liblapack.so is 3742k (expected >4000k)

     Follow the instructions in the KNOWN PROBLEMS section of the file
     numpy/INSTALL.txt.
*********************************************************************

The INSTALL file is missing :-( I wonder if this is really a problem 
or just the result of stripping the binary (assuming RPM stripped 
it). I rebuilt lapack3 but the binary is still under 4MB. Let me 
know what you think.

Below is the rest of the relevant output. BTW, thanks for your 
responsiveness to this issue.

Chris
