Apple's normal recommendation is -Os, I'm fairly certain that -O -g  
aren't meant to be instructive in that article.

It's probably better to have it disabled by default.

The debug information is a not-insignificant amount of space.

(here's a non-macports example of one library I have installed:
-rwxr-xr-x     1 root  wheel        3M Jan 18 08:20 QtCore*
-rwxr-xr-x     1 root  wheel       43M Jan 18 08:20 QtCore_debug*)
