So yesterday I installed scipy and I successfully used fsolve per the 
example in the docs.  Today when I logged back into my machine, fsolve 
had stopped working though.

 >>> scipy.optimize.fsolve(func,1)
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/usr/local/lib/python2.3/site-packages/scipy_base/ppimport.py", 
line 270, in __getattr__
     module = self._ppimport_importer()
   File "/usr/local/lib/python2.3/site-packages/scipy_base/ppimport.py", 
line 243, in _ppimport_importer
     module = __import__(name,None,None,['*'])
line 11, in ?
     from lbfgsb import fmin_l_bfgs_b
"/usr/local/lib/python2.3/site-packages/scipy/optimize/lbfgsb.py", line 
28, in ?
     import _lbfgsb
ImportError: /usr/local/lib/libptf77blas.so.1: Undefined symbol 

I'm wondering if the environment variables used in the build still need 
to be set to continue using this package.  Anyone know for sure?
