We've been over this before, but for fork's sake, the gist of it is that 
Macports may install non-universal binaries (possibly breaking existing 
applications which dynamically link to libraries) and you might end up with 
multiple different versions of gcc, libstdc++  (again possibly breaking 
existing applications which dynamically link to libraries), etc. on your 
machine.

If Octave works with Macports, and if some people find that easier, great. But 
let's make sure it works without it - and it's really not hard to do.
