I would suggest using the binary installation for Macs.  The IBM
compiler produces code that runs 50% faster than that produced by the
GNU compilers.  The binary installation is done simply

     perl install.pl -n

where the -n says binary (network).  If you are going to develop code
inside AIPS so that you must have a local compiler, then it is
important to get a GNU compiler to work.  We are using GNU 3.4.4 onm y
Linux machine and there seems to be no trouble with it.
Unfortunately, we are not really testing GNU compilers anymore since
we use Intel for Linux and IBM for Macs.
