BTW: I saw the three (?) build attempts in your original log, that's
a nice feature!

Oh, that's interesting.
Now we just have to find out what's different when building
automatically :)

AFAIK it doesn't, there's also a bug report whith some discussions
about this: #532805

What I have seen is upstream build systems getting confused by
passing -jN to dpkg-buildpackage nevertheless; but that shouldn't
happend without explicitly setting it.

Which differences do you actually see? I've copied the three
dpkg-buildpackage parts from
http://people.debian.org/~lucas/logs/2009-10-16/libgstreamer-perl_0.15-1_lsid64.buildlog
and diffed them, and I don't see anything spectacular.

From my build log:
chmod 755 blib/arch/auto/GStreamer/GStreamer.so
cp GStreamer.bs blib/arch/auto/GStreamer/GStreamer.bs
chmod 644 blib/arch/auto/GStreamer/GStreamer.bs
Generating POD...
Loaded 6 extra types from doctypes

"Parsing Parsing XS files..." is in the generated Makefile; but
that's only about building anyway.

Hm, somethings weird here.


Cheers,
