The subsequent mapnik (3.0.0+ds-1) upload failed to build on the same
archs again. I've just pushed a change to exclude mips* from the list of
architectures that will prevent them from building mapnik.

mapnik still can't migrate because the old python-mapnik binaries
(#790043) and the outstanding RC bugs.

https://release.debian.org/migration/testing.pl?package=mapnik

I'd like to upload mapnik (3.0.0+ds-2) as it currently exists in git to
get the mips* exclusion and static libraries for the python-mapnik build
into the archive. After that we can request removal of the mapnik
package for mips & mipsel.

Jérémy, do you have anything you want to add before the upload?

I suspect the failure on kfreebsd-i386 is caused by exhausting the 32bit
address space, but since it's not a release architecture we don't have
to worry about it much.

Kind Regards,
