Yes, nothing can be done here until someone comes up with a patch (it's a big change and probably will never happen). Either update to KDE PIM 16.12.0, or downgrade gpgme to lastest stable version.
It looks like calligra:4 is your only kdepimlibs rdep, so you could unmerge that or upgrade to calligra:5 (currently 3.0.0 only in kde overlay).
Actually, another solution for you would be calligra[-pim].
