Then pay attention to configure output, you should see something like: checking for python... python checking for python SDK... yes checking if python SDK is usable... yes If those tests don't succeed, no need to rebuild CS or CEL, you won't have python support. Note that you may need to use Cygwin-type path in your export command, like: (assuming Python is installed in C:\Python25) export PYTHON=/cygdrive/c/Python25/python.exe If it doesn't work, try with export PYTHON="C:\Python25\python.exe" You may also try to add C:\Python25 to your PATH environment variable. Once the tests cited above succeed, you'll have to jam/rebuild CS, then reconfigure and rebuild CEL too.
