How to install scikit-learn on heroku cedar?
===

I'v successfully installed numpy and scipy using the method described in [this][1] answer. Then I wanted to add scikit-learn so at first I tried adding `scikit-learn==0.11` to the requirements.txt and when pushed to heroku I got an error message:

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

So I've added to `LD_LIBRARY_PATH` the path where I have `liblapack.so.3gf` but then I got this:

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

I believe that heroku doesn't have fortran compiler, but maybe I wrong. How can I resolve this?
