# 20220316 bkw: derp. fix broken symlinks.
# 20210824 bkw: update for v2.0.99.2, aka 2.1rc1, because 2.0 won't
# build on -current and other distros have been shipping 2.1 betas and
# release candidates for years now.

# Most of the executables have 2 names each, short and long, e.g. mpp
# and makepp. install.pl installs them as hardlinks, which is kinda weird
# for a Slack package. Not sure they'd cause any problems, but I *know*
# symlinks work correctly, so:
sed -i \
    -e 's,^ *link\>,symlink,' \
    install.pl

# configure/make is just a wrapper around install.pl. Skip the tests,
# because they spam /usr/include and don't even clean up after themselves.
