Comment (by kencu):

 Glad it works. MacPorts is very powerful, and helps these older systems a

 To change the optflags, you need to edit the port's Portfile, like this:
 bbedit `port file MYPORT`
 if there are already optflags written into the portfile, you can change
 configure.optflags -03
 #or whatever
 otherwise add the line yourself.

 It doesn't always work, depending on the build system, but it will work
 with a large majority of ports.

 To see what ports do when that doesn't work, go to the top of the port
 tree, for example like this:
 cd `port dir llvm-3.7`/../../
 and take a look around with your searcher of choice. I like
 {{{the_silver_searcher}}} so I would do
 ag configure.optflags .
 and you can see what others have done in various ports to monkey with
