Here are the outputs of cygcheck (as advised in http://cygwin.com/ml/cygwin/2009-10/msg00004.html) and nm.

I have found cyglapack.dll in lib/lapack/cygblas.dll.....



$ cygcheck /lib/python2.5/site-packages/numpy/linalg/lapack_lite.dll 
Error: could not find cyglapack.dll

$ nm /lib/python2.5/site-packages/numpy/linalg/lapack_lite.dll
