# block on makemaker versions earlier than that in the 5.8.2 core. in
# actuality, this should be handled in the perl ebuild, so every perl
# ebuild should block versions of MakeMaker older than the one it
# carries. in the meantime, since we have dumped support for MakeMaker
# <6.11 and the associated broken DESTDIR handling, block here to save
# people from sandbox trouble.
