Yes it depends on stabilisation of new revbump.
Same error here.
Unmasking (with ~amd64) version 2016-r6 seems to solve this problem.
If you have the same problem please vote for this bug.
According to this comment: https://bugs.gentoo.org/644802#c5 the texlive-core-2016-r6 is now stable for amd64, no need to unmask ~amd64.
That seems to have fixed the compile errors for me.
I did an "emerge --sync && emerge -uDN world" this morning and emerge installed texlive-core-2016-r6 without unmasking. :-)
Works for me.
This depends on bug 646638 now for the remaining arches.
Fixed in 2016-r6 and 2017-r3.
