The UMFPACK maessage just tells you that your installation has no module 
scipy.linsolve.umfpack (the build of this was disabled when scipy was 
compliled) which shouldn't be something to worry about as long as you 
don't want to use it.

Does this mean the test didn't finish? Did you see something like


#----------------------------------------------------------------------#

 >>> scipy.test()

..zcopy:n=3
.............zscal:n=4
....zswap:n=4
..zswap:n=3
...Result may be inaccurate, approximate err = 6.99076835435e-09

WARNING: cblas module is empty

See scipy/INSTALL.txt for troubleshooting.
Notes:
* If atlas library is not found by numpy/distutils/system_info.py,
   then scipy uses fblas instead of cblas.
