 When attempting to install py27-pandas on Jan 15, 2014 I had errors trying
 to install py27-scipy.

 The error in the log referred to missing a fortran compiler.

 I installed a fortran compiler with 'sudo port install f95'. This fortran
 compiler was still not recognized when install py27-scipy. I did not see a
 f77 or f90 compiler (from the scipy log) listed when I ran 'sudo port
 search fortran'.

 I ended up installing gfortran 4.8.2 from binaries available at this
 location: http://gcc.gnu.org/wiki/GFortranBinariesMacOS

 After installing gfortran, I had to make 2 symlinks for the py27-scipy to
 install:

 {{{
 sudo ln -s /usr/local/gfortran/bin/gfortran /opt/local/bin/gfortran
 sudo ln -s /opt/local/bin/gfortran/gfortran /opt/local/bin/gfortran
 /gfortran-mp-4.8
 }}}

 After manually installing gfortran and the 2 symlinks, I was able to
 successfully run 'sudo port install py27-pandas'.

 I verified that py27-scipy was working by typing in the ipython commands
 shown at: http://www.scipy.org/getting-started.html

 I was able successfully create and save the graph shown in the example.

Comment:

 Please don't install things in /usr/local when using MacPorts; it causes
 problems. See wiki:FAQ#usrlocal.
