It all works as expected:
>>> from ctypes import CDLL, c_char_p
>>> CDLL('geos.dll')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "c:\Python27\lib\ctypes\__init__.py", line 365, in __init__
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found
>>> import os
>>> os.environ['PATH'] += ';z:\\path\\to\\geos'
>>> CDLL('geos.dll')
<CDLL 'geos.dll', handle 6bf80000 at 1765250>
>>> geos = CDLL('geos.dll')
>>> geos.GEOSversion.restype = c_char_p
>>> geos.GEOSversion()
'3.3.5-CAPI-1.7.5'
