libnl3's documentation generation system saw an overhaul in 3.2.10 with a new dependency on media-gfx/mscgen, so please test and keyword: =dev-libs/libnl-3.2.10 media-gfx/mscgen Target KEYWORDS: "~alpha ~amd64 ~arm ~hppa ~ia64 ~ppc ~ppc64 ~s390 ~sh ~sparc ~x86 ~amd64-linux ~ia64-linux ~x86-linux"
~arm added
media-gfx/mscgen does not appear to work properly on HPPA (test suite failures, segmentation faults when used to build the libnl documentation) so I have masked USE=doc for dev-libs/libnl in the HPPA profiles. Marked ~hppa.
Keyword ~ppc ~ppc64
When the 3.2.14 release is fixed upstream (see [URL]), this will probably be obsolete, as the docs will be distributed separately and pre-compiled.
3.2.14 does indeed do away with all the documentation building deps.
