Thanks; the force deactivation was the tip I was looking for. I somehow
was focussing on the dependencies instead of the main program.

Unfortunately, my problem remains. I used a Linux system for now, so I'm
OK for now. I'll have a look later and file a bugreport at the MacPorts
site. (a quick search only gave a related issues with Python 2.6, but
did not give me a solution).

Mostly I first have to figure out what Python's "destroot" is doing in
the first place. I would only expect /usr/bin/install and chmod
commands, but I also see lines starting with "Compiling ..." in the
debug output. Perhaps that's just "compiling" .py to .pyc. The error was
caused by a command starting with "../python.exe
./scripts/", which makes me suspicious (running a build
script in the destroot phase?)

Thanks. I got the same problem on two machines. Not really surprising,
since they have rougly the same MacPorts. It is encouraging to know it
can be done :)

Perhaps it's a Lion issue.
