Comment:

 I do not see the reason to change the shared_lib_extension definition in
 {{{ numpy/distutils/fcompiler/__init__.py }}}. That location does not
 affect the detection of atlas library. But I do not know what happens
 under Windows and Mac and with other libraries. Reverting that change
 means that the value of {{{ shared_lib_extension }}} will confirm to the
 PEP 3149 (http://www.python.org/dev/peps/pep-3149/).

 Changing the {{{ so_ext }}} variable in {{{ numpy/distutils/system_info.py
 }}} was sufficient for Python3.2 to find the atlas library:
 {{{
 so_ext = '.' + distutils.sysconfig.get_config_var('SO').split('.')[-1]
 }}}

 That is still incorrect because it assumes that the library is not from a
 Python extension. In order to address PEP 3149, this should really be
 something like for Python 3.2+:
 {{{
 >>> import distutils.sysconfig
 >>> so_ext = [distutils.sysconfig.get_config_var('SO'), '.' +
 distutils.sysconfig.get_config_var('SO').split('.')[-1]]
 >>> so_ext
 ['.cpython-32m.so', '.so']
 }}}

 But that messes the rest of the code that expects so_ext as a str not
 list. Also under earlier Python versions it is:
 {{{
 ['.so', '.so']
 }}}
