Linking time may be an issue as well. Do the "prelink" tools for C
libraries help at all with scipy? Or, how much of the load time is
loading compiled python code, and how much is loading shared
libraries?

For the OP: is python perhaps recompiling the .py files every time?
Normally python produces a .pyc to accompany every .py file, but if
the installation directory is not writeable, this may not be possible.
Normally installation of python packages premakes all these files, but
if you have installed it in some unusual fashion, they could be
missing.
