pkgsrc by default initializes the environment to the C locale, so
setting it in the outside environment shouldn't affect anything. Try
'make show-var VARNAME=MAKE_ENV':

LANG=C LC_ALL=C LC_COLLATE=C LC_CTYPE=C LC_MESSAGES=C LC_MONETARY=C LC_NUMERIC=C LC_TIME=C

The usual workaround is to add this:

ALL_ENV+=     LC_ALL=en_US.UTF-8

at the _bottom_ of a pkgsrc Makefile, after bsd.pkg.mk (to override
these settings, which are only set in bsd.pkg.mk). I tried that for
lang/ghc98 and it didn't fix the problem.
