# Matplotlib tries to find Tcl/Tk by opening a Tk window and asking the
# corresponding interpreter object for its library paths. This fails if
# `$DISPLAY` is not set. The fallback option assumes that Tcl/Tk are both
# installed under the same path which is not true in Nix.
# With the following patch we just hard-code these paths into the install
# script.
