I've stuck to using MacPorts , more within my comfort zone for the Mac, and generally takes care of all dependencies consistently, although releases lag behind a bit.  Hopefully the package maintainer will pick up on Gilles' forthcoming 2.3.0 release .... 
 
I build from the git repo. macports is far easier, and i would recommend sticking to that.

Ha. I had no idea hugin was in macports. They also have a standalone application, which is how i've used it in the passed. I'm sure the macports version is the same.

I also have the 'panoramagui'  KDE application installed, and similarly that's giving errors about not being able to find the Hugin component 'autooptimiser', so this is probably not a Digikam issue. 

How are you launching digikam, though command line, or through finder? 

If you launch it through finder, i don't believe any shell modifications to your path are passed to the application. If you launch it through the command line, 
 $ /Applications/MacPorts/KDE4/digikam.app/Contents/MacOS/digikam

then your shell environment modifications will be passed to digikam, and it *should* find those executables. Just to be sure, before you launch digikam through the command line, simply try executing 'align_image_stack -h' to see if your shell can see that executable.

I don't think anything needs tweeking on your end, I believe its a matter of how you lunch digika (see above) -- at least for the time being, perhaps in the future a more cross-plartform method of finding these executables will be put in place).

i assume they are similar, but since i haven't got digikam's pano tool working, i can't really say.
