make bustedisn't an option on source builds. Not a big deal but already had to tweak the stable Arch package to dodge it.
v0.10.1in a week or so as needed, hopefully with anything Homebrew or other packagers need too.
--without-system-luarockswould cause the
makeprocess to fetch and bundle them all with SILE without telling
brewanything about them.
brewis stepping in and giving a sort of sand boxed system path so it can handle the downloading, checksumming, etc. itself rather than fetching the deps at build time.
