[Haskell-cafe] Damn you hmatrix

[Yotam Ohad]

I did not see this guide, but even when I follow the instruction when I try
to install hmatrix as in the last step of the guide and get a /missing C
library: libgfortran-3.
All the actions I described in the first email have resulted in the same
results.
