How to install scikit-learn on the cedar hero?

I have successfully installed numpy and scipy using the method described in this . Then I wanted to add scikit-learn, so first I tried adding scikit-learn==0.11.txt to the requirements file and when I clicked on the hero I got an error message:

ImportError: liblapack.so.3gf: cannot open shared object file: No such file or directory

So, I added to the LD_LIBRARY_PATHpath where I have it liblapack.so.3gf, but then I got the following:

ImportError: libgfortran.so.3: cannot open shared object file: No such file or directory

I believe geroku does not have a fortran compiler, but maybe I'm wrong. How can i solve this?
