It is stated in the installation section of the tutorial PDF that python 2.3 or higher and numpy 1.0 or higher are required. I have fulfilled these requirements. Yet, when I check the installation by running from PyML import * in my python 2 interpreter, I get the error: ImportError: No module named _ckernel I am guessing the issue has something to do with the fact that "there is some C++ code so the library is not automatically portable". Can anyone lend me a hand?
