scipy error undefined symbol: lsame_

[gerardob]

I installed scipy (and all the required libraries) and the following error
appears when i tried run a simple example which uses the optimize package of
scipy. I tried also numpy alone and it works ( at least for printing
numpy.array([10,20,10]))

error:

Traceback (most recent call last):
File "main_test.py", line 2, in <module>
from scipy import optimize
File
"/home/gberbeglia/python/Python-2.6.5/lib/python2.6/site-packages/scipy/optimize/__init__.py",
line 11, in <module>
from lbfgsb import fmin_l_bfgs_b
File
"/home/gberbeglia/python/Python-2.6.5/lib/python2.6/site-packages/scipy/optimize/lbfgsb.py",
line 30, in <module>
import _lbfgsb
ImportError:
/home/gberbeglia/python/Python-2.6.5/lib/python2.6/site-packages/scipy/optimize/_lbfgsb.so:
undefined symbol: lsame_

Any ideas on how to solve this problem? Thanks.

PS: the example is below:

import numpy
from scipy import optimize

a = numpy.array([10,20,10])
print a

def f_(x):
return x*x

x,f,d = optimize.fmin_l_bfgs_b(f_,[0.1],fprime=None, approx_grad = True,
bounds = [(-10000,10000)], iprint=30, maxfun=150000)

Um... The snip works perfect on my computer. Just copy and paste.
What libraries are you talking about you had to download? Are you on
windows or linux? On windows you dont need to download anything but
numpy and scipy packages.

This is a FORTRAN symbol. It means that this extension module was not
linked correctly to the FORTRAN standard library appropriate for your
system.

If you need more help, please ask scipy questions on the scipy mailing list.
