This "... create-home-directory? ..." commit is eb56ee027 actually:

http://git.savannah.gnu.org/cgit/guix.git/commit/?id=eb56ee027b4c6b5682f69fa885d16e55c4495bd8

I think that commit is an ABI-breaking thing.  Try to do "make clean-go"
and remake the guix checkout again.

Specifically, that commit didn't touch (gnu services base) module, so
'guix-build-accounts' procedure still produces guixbuilder users
accounts in an "old" format.  It's just my guess though, but "make
clean-go" should work.
