What does $ cygcheck cyggsl-0.dll
return for you? This should be your problem.
As I said I suspect lapack is not in your path, or there is some
problem loading the blas dll.

$ cygcheck cyggsl-0.dll
Found: d:\cygwin\bin\cyggsl-0.dll
d:\cygwin\bin\cyggsl-0.dll
  d:\cygwin\lib\lapack\cygblas.dll
    d:\cygwin\bin\cygwin1.dll
      C:\WINDOWS\system32\ADVAPI32.DLL
        C:\WINDOWS\system32\ntdll.dll
        C:\WINDOWS\system32\KERNEL32.dll
        C:\WINDOWS\system32\RPCRT4.dll
          C:\WINDOWS\system32\Secur32.dll
