Ming,

If you're interested in contributing changes to Octave sources
you should not be changing the Octave files installed by macports
but rather clone the Octave mercurial repository and working there:
http://hg.savannah.gnu.org/hgweb/octave/

If rather than to core Octave you wish to add functionalities to an existing 
Octave-Forge package you should check out the subversion repository instead:
http://sourceforge.net/p/octave/code/HEAD/tree/

this section of the manual may provide you with useful info:
http://www.gnu.org/software/octave/doc/interpreter/Contributing-Guidelines.html

And also these sections in the wiki might help:
http://wiki.octave.org/Main_Page#Building_Octave
http://wiki.octave.org/Main_Page#Octave-Forge

HTH,
c.

P.S. BTW, macports installs your files in /opt/local. 
 to see where a particular .m file is located on your machine type
 
 >> which function_name

 at the Octave prompt. while typing 

 >> edit function_name

 will open (a copy of) the source file in your default editor.
