# XXX Temporary hack for a broken sdl2_mixer or readline package in Homebrew.
# sdl2_mixer's pkg-config file requires readline, but the readline pkg-config
# file isn't installed to /usr/local/lib/pkgconfig, meaning it can't be found.
# I don't know the logic behind what gets symlinked into /usr/local/lib/pkgconfig
# so I don't know who's at fault here, but the hacky way around it is to set
# $PKG_CONFIG_PATH to point to readline's pkg-config directory. This only
# happens if $PKG_CONFIG_PATH isn't already set.
