I was considering fixing this bug while building a small QA upload for fixing a l10n related bug in anubis.
However, after looking at it, I found that indeed anubis build-depends on libgpgme-dev.....which depends on libgpgme6. This explains why the default build of anubis makes it depend on libgpgme6 instead of libgpgme11. As I have no idea of the consequences of a possible Build-Depends change, I leave this unchanged. This should be investigated further if comeone adopts the package. --
