I didn't think to do that, but I bet that would probably work (and is a
better solution than recompiling every time). Although I would tend to
prefer this form:
if [ "${output_file}" -nt xmonad.hs ] && [ "${output_file}" -nt
/usr/local/bin/xmonad ]; then
...
I prefer that over the form mentioned as it avoids some potential
ambiguity/maintenance issues in the long run. Here's a relevant entry
from the shellcheck wiki on github.

My apologies for the confusion, it would be ~/.xmonad/build by default.
Everything goes in ~/.xmonad by default. I have configured my setup so
everything isn't in ~/.xmonad, but rather split up into different
directories via XMONAD_CACHE_DIR, XMONAD_CONFIG_DIR, and
XMONAD_DATA_DIR. I prefer to follow the XDG base directory specification
when possible so that config files are in ~/.config, user scripts are in
~/.local/bin, etc.
Here are the relevant bits in ~/.profile (sourced by ~/.xsession) that I
use to make that work:
export \
XDG_BIN_HOME="${HOME}/.local/bin" \
XDG_CACHE_HOME="${HOME}/.cache" \
XDG_CONFIG_HOME="${HOME}/.config" \
XDG_DATA_HOME="${HOME}/.local/share" \
XDG_STATE_HOME="${HOME}/.local/state"
export \
XMONAD_CACHE_DIR="${XDG_CACHE_HOME}/xmonad" \
XMONAD_CONFIG_DIR="${XDG_CONFIG_HOME}/xmonad" \
XMONAD_DATA_DIR="${XDG_DATA_HOME}/xmonad"
Sorry about the mix-up. Either configuring it as above and, to be on the
safe side, making sure that $XMONAD_*_DIR all exist, should work. Or
using ~/.xmonad if you don't want it to be separated like that (this is
also easier to deal with if xmonad or the XDG base directory
specification are unfamiliar territory, since it's all in one location).
Also, you'll need to have an xmonad-config.cabal if you don't have it
already, either in ~/.config/xmonad/xmonad-config.cabal if you used the
exports above or ~/.xmonad/xmonad-config.cabal. An example config can be
found at /usr/local/share/examples/xmonad-0.17.0/xmonad-config.cabal.
I'd guess the absence of that file might be causing 'cabal: Unknown
package "exe".'
Here's an updated diff implementing your suggested change. Thanks for
your time and I hope it helps. :)
