As part of my research, I have been compiling and running a model (all fortran 90 scripts) on our university's Linux cluster test module. I purchased a MacBook about a year ago, and would like to learn how to compile and run my model on osx. To build my model in Linux, I set:
1. env. variables for MPI and NETCDF directories
2. flags for -llapack -lblas
3. user-specified fortran and c compiler overrides (fc and cc)
A colleague advised me to 'use gfortran as part of gcc 4.3+. To be installed by use of fink', but I honestly do not quite know where to begin doing all of this on my MacBook. If you can provide any guidance, point me to another forum / reference, I would greatly appreciate your time. Thanks!

Not really sure if anyone on LinuxQuestions can give you much assistance with OSX on a Macbook. Have you checked any of the OSX/Mac forums??
You need to install xcode, from the install DVD, with that, you get gcc, ld, etc. and an IDE. Then you can compile whatever you want yourself, with gcc from the command line. If you need libraries (lapack, blas), you may want to install them via fink or macports, which are package managers.

A other option is to buy MAC OSX Snow leopard bible , it is User guide for Snow leopard .
One of the chapters is called go behind the basics in that chapter they learns you the basics of Apple script , Fink ,Mac ports and so on.
Of course if you use Snow leopard.

One of the major shortcomings of XCode for a scientific user is that it does not iunclude gfortran by default. I don't do very much with OS X, but I've dabbled with it a bit and others in my work place use it extensively. We've found that the gfortran builds from http://hpc.sourceforge.net are about the best way to get gfortran running on Macs. Note you will need XCode installed to use them.
BTW, your original post talks about MPI. Are you planning to run your code in parallel using MPI? I believe that OpenMPI installs and runs OK on OS X, but have never actually tried it.
