I have been using the gcc compiler from http://hpc.sourceforge.net/index.php for 6 years. Unfortunately they are not using the most up to date compiler. I have already installed gcc 4.8.3 from mac port. Is mac ports compiler as reliable as the one from http://hpc.sourceforge.net/index.php?
In the past I have had reliability issues with certain mac port products especially their version of codeblocks. If mac port's gcc 4.8.3 also has reliability issues I think I would rather use the older version of gcc or download gcc from somewhere else.
