# util-linux renders its man pages from asciidoc, which this port does not have,
# so man3 does not exist. The util-linux-libs split moves it out of pkgdir and
# then back in -- TWO places, and removing only the first fails on the second.
#
# Both moves go. Nothing is left conditional: if the directory is never created,
# a guard around moving it is a guard around nothing, and it would read as if
# the man pages were sometimes present.
#
# Same shape as libxml2's docs split, pam's PDFs, libuv's man page and cmake's
# emacs byte-compilation: a failure on a path at the end of package(), after a
# compile that worked. Seventh time.
