I worked . Thanks!!
there was no error during the installation. But when I tried to import
scipy.signal, I got the following error

>>> import scipy.signal
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.5/site-packages/scipy/signal/__init__.py",
line 10, in <module>
    from filter_design import *
  File
"/usr/local/lib/python2.5/site-packages/scipy/signal/filter_design.py", line
9, in <module>
    from scipy import special, optimize
  File "/usr/local/lib/python2.5/site-packages/scipy/optimize/__init__.py",
line 11, in <module>
    from lbfgsb import fmin_l_bfgs_b
  File "/usr/local/lib/python2.5/site-packages/scipy/optimize/lbfgsb.py",
line 30, in <module>
    import _lbfgsb
ImportError:
/usr/local/lib/python2.5/site-packages/scipy/optimize/_lbfgsb.so: undefined
symbol: _gfortran_st_write_done

How I can fix it?
Thanks
