It is as I expected: you are trying to do a mixed installation, octave 
from the dmg package, and other things from MacPorts.  This is not 
advised.  Technically, you should be able to install both octave (dmg 
install) and the image package from octave-forge, but you would need to 
resolve all other dependencies manually (such as development tools like 
gcc, and other libraries/programs like ImageMagick), and make sure the 
configuration and environment was correct for everything.  This is 
probably where you had some trouble.  MacPorts can take care of this for 
you, but you should only use MacPorts to install all the parts.  Do not 
mix and match.

I recommend that you uninstall the octave.app from the dmg download and 
anything else you installed manually (ImageMagick?).  Make sure your 
MacPorts installation is working by installing and testing something 
small, say "gv" (ghostview to view postscript files).  Then install 
octave and octave-image using the commands I posted previously (above).
