Ok, the above looks like a comment of mine :). Actually I didn't
finish this task yet. Once I have done it, I'll report the results
here.

Something like this?

http://wiki.maemo.org/PyMaemo

(sorry for not making it widely known yet; I had implicitly make it
known on another python-hildondesktop thread.)

The link you sent are from the older wiki; we are not using it
anymore, but some texts are still there for archival and reference
while we don't review all info there.

The autobuilder does not check for *runtime* dependencies, only *build
time* ones. This is not a big issue (I think autobuilders from other
distros do the same, but I'm not sure), as long as it is
documented/promoted enough as Quim suggested.

This can have a lot of reasons, one of them being that they simply
don't have the extras-devel repository on their local sbox
/etc/apt/sources.list.

And if it is a runtime dependency problem, the build will finish ok,
although the package will not be installable. If this is the case, it
shows yet another QA issue: that the built packages might not have
been tested for correct installation/removal.

I think the original maintainer has said that it should not be
necessary anymore and that the package that broke because of it
will/was fixed (if I remember correctly)

I don't think Quim himself had the problems, but possibly he
"aggregated" the issues from other sources. Quim: is that the case?
