# bmon is by the author of libnl, but apparently bmon only works with
# 0.x versions of libnl (specifically, it won't build with the libnl 1.1
# that's included in Slackware 13). There's no --disable-libnl or similar
# option to the configure script, so we have to patch it.
patch -p1 < $CWD/disable_libnl.diff

# missing = signs... sigh.
