This wasn't obvious to me either.

To use your own blas/lapck in scipy, you need to put a site.cfg file  
in the distutils directory of your numpy installation.

So if you installed numpy with --home=$HOME
it should produce a distutils directory at $HOME/lib/python/numpy/ 
distutils or $HOME/lib64/python/numpy/distutils

If you want to build scipy with the same site.cfg as you used to  
build numpy, then, assuming the root source numpy directory is $PYSRC/ 

cp $PYSRC/numpy/numpy/distutils/site.cfg $HOME/lib[64]/python/numpy/ 

Hope this helps.
