what it the output of:

$ cygcheck /usr/lib/python2.7/site-packages/numpy/linalg/lapack_lite.dll

   E:\cygwin\bin\cygwin1.dll
     C:\Windows\system32\KERNEL32.dll
[cut]
   E:\cygwin\lib\lapack\cyglapack-0.dll
     E:\cygwin\bin\cyggcc_s-1.dll
     E:\cygwin\bin\cyggfortran-3.dll
     E:\cygwin\lib\lapack\cygblas-0.dll
