Interesting. I will run a script here to check python packages in
Diablo that should fail to install in fremantle due to missing
dependencies, and check which of these dependencies are related to
PyMaemo packages.

I think the above two shows that the extras-devel system needs to be
more documented/promoted ?

Possibly it is due to some other dependency that actually needs it,
and not necessarily a direct dependency. But see below, this package
is already on fremantle extras-devel for some time.

Personally I like bug reports because they allow me to track my
progress on fixing bugs, but sending a message here on in the
pymaemo-developers list is also OK (I can even create the bug report
myself later).

* python2.5-hildondesktop:   it is now in fremantle extras-devel since
the weekend (sorry for not making this public yet, I was working on
writing an example plugin because this new version WILL require
porting from packages and will not work without changes

* python-mokoui : no idea which package is this. Jeremiah/Niels: can
it be added the your automatic building task?

* python-support >=0.90.0 : it is already there since the PyMaemo beta
release (version 1.0.2maemo1). I think the person who reported this
did not have the extras-devel repository added to his/her target
sources.list.

BTW, all python dependencies maintained by PyMaemo once named
"python2.5-XXX" must be renamed to "python-XXX" for fremantle. This is
necessary because we now follow Debian Python packaging policy as
close as possible. But note that the old package names (python2.5-XXX)
should still work.
