Use stow to mirror everything into /usr/local, that also makes sure  
nothing is double and provides a clean uninstall mechanism. Also I  
think it should be possible to put macports somewhere else than opt/ 
local. At least internally everything is built depending on a prefix  
variable, and not hardcoded to /opt/local. Though it is generally  
preferrable to put things into some /opt path and stow, so it's easy  
to roll back in case of mess-ups.

Also octave should soon be 2.9.10 on macports. Though I am not sure  
if octave-forge will still work then, due to the new mechanism of  
octave-forge. It is relatively easy to install octave-forge by hand  
though. Same as gnuplot which is only 4.0 in macports, and 4.2 has  
image support which is much better than imagemagick. So things might  
have to be added by hand into the package. Also not 100% sure to add  
a shell phase to the package for stow, anyone?
