# Chez Scheme depends on make, gcc, ncurses, and X11 according to:
# https://github.com/cisco/ChezScheme/blob/06f858f9a505b9d6fb6ca1ac97234927cb2dc641/BUILDING#L41-L44
# `musl-dev` is Alpine's version of `libc-dev`.
# `openssl` is needed to `wget` from `https://github.com`.
# Even curl is needed!  This seems kind of sketchy:
# https://github.com/cisco/ChezScheme/blob/06f858f9a505b9d6fb6ca1ac97234927cb2dc641/configure#L305

# Ultimately there is a build error, but it doesn't seem to impact anything:
# Exception in $fasl-file-equal?: code comparison failed while comparing ../boot/a6le/sbb and ../boot/a6le/petite.boot within fasl entry 103
# make[4]: *** [Mf-base:266: checkboot] Error 255
