You can build wrapitk with an installed ITK - no need to keep the ITK  
source tree.

It's linked with ITK, and it uses the headers from itk during the  
build, nothing more. Just as any normal application using a normal  
library.

I have a separate dir for wrapitk.

I built it as a separate package. I think that would be a good thing  
to have it as a separate package in macport too.

I'm quite sure it won't work.

No, that's not necessary, and is likely to NOT work.

No: it can take everything it needs from the installed ITK.

Right.

Really, building wrapitk is not that difficult. It builds fine with  
the installed ITK, CableSwig, Python, Java, Tcl, doxygen and swig. And  
from my packaging experience (for mandriva), it's easier to package  
CableSwig, ITK and WrapITK in 3 different packages than into a single  
one, at least because it decreases the build time for a single  
packgage. Also, wrapitk 0.3 builds fine with "make -j16" - that's what  
I'm using on my new host. I think you're not doing parallel build at  
this time in your package...

Can't you simply make the wrapitk package depend on the ITK package,  
including for the build?

The only difficult part, I think, is how to make the packages so that  
both wrapitk versions can be there. Or, if that's not possible, how to  
define which one should be there.
