[SciPy-dev] Building numpy/scipy on RHEL5 OR CentOS5

[Michael Hearne]

My apologies to everyone - I figured out the problem.  I was performing 
the build procedure as myself, after setting UMFPACK="None", but using 
sudo to install.  It didn't occur to me until just now that running as 
root meant that my environment variable wouldn't be visible in the root 
shell.  Duh.

That being said, can I make a suggestion that setup.py for scipy take an 
option that can turn UMFPACK off, instead of the user having to remember 
to do it in the shell, and causing him or herself the same sort of 
confusion I just caused?

It would also be great to have a less convoluted build procedure for 
BLAS/LAPACK, but I'll take one thing at a time.

Also, since Phil seems not to have to set this variable, is there 
something I can provide developers that would help them understand why 
my RHEL5 system seems to require that I set it?

Thanks for everyone's help,
