Thanks for letting me know. And, yes, I am definitely interested :).

I'll definitely have a look. I just can't do it right now because I'm at
work :).

Since we're talking about Qt anyway: There is a strange FTBFS of qt4-x11
which I am seeing on powerpcspe [1]:

Do you have any idea why this happens? Could there be possibly a build dependency be
missing? This particular package definitely built successfully on powerpcspe in
the past (I did a testbuild with 4:4.8.5+git209-g718fae5+dfsg-1 which previously
built fine), so unless there is something broken in the toolchain (which I also
don't think since powerpcspe basically uses the powerpc backend of gcc), I think
that qt4-x11 depends on these precompiled headers being present from an external
package which might not be there unless Qt5 is fully bootstrapped.

Thanks for your help!

Adrian
