[SciPy-user] problem installing sciPy

I have not looked through your error messages closely, but perhaps it's
worth taking a step back and trying an easier install.

As David mentioned, SciPy supports Python 2.3, which should be installed on
your system.  I'd recommend just going with that.  A basic install:
0) Read scipy-0.6.0/INSTALL.txt.  (if you haven't done so already)
     It includes the basic install instructions and various install options.
1) Install lapack through an rpm.  You can find them here:
2) Install numpy from the tarball.  (I appears you already did this
successfully once.)
3) Install scipy 0.6.0 from the tarball.

That should be sufficient to get you up and running.

As you mentioned, there are a lot of messages flying past during the build,
some of which appear to be errors.  If the build succeeds you can probably
ignore those messages.  They're usually along the lines of: couldn't find
ideal fortran compiler but found this one instead...
