cmake in cygwin: cyglto_plugin.dll not found - cygwin

Question

I am trying to get a Fortran 90 program to compile under Windows. I have already successfully done so under Linux.
I am using the 'Babun' windows shell, which is basically a wrapper for cygwin: https://github.com/babun/babun
When I try and run cmake, I get the following:
-- The Fortran compiler identification is GNU
-- Check for working Fortran compiler: /usr/bin/gfortran.exe
-- Check for working Fortran compiler: /usr/bin/gfortran.exe -- broken
CMake Error at /usr/share/cmake-2.8.9/Modules/CMakeTestFortranCompiler.cmake:40 (MESSAGE):
The Fortran compiler "/usr/bin/gfortran.exe" is not able to compile a
simple test program.
It fails with the following output:

What package does this cyglto_plugin.dll belong to? What dependencies am I missing?
Thanks!
