Thanks Simon (and Prof Ripley, offline). The --static modifier needs to
be added in two places in configure.ac, which leads to it being added in
two places in configure.
If anyone wants to build from source, you could get the CRAN release
plus this modification using
remotes::install_github("dmurdoch/rgl using configpatch")

>>> That looks like a symbol in the harfbuzz lib. rgl doesn't reference it directly, I think FreeType does. I don't know what you need to do to fix this, but maybe that's enough of a hint.

>> XQuartz doesn't include libharfbuzz, so I doubt that it's libfreetype depends on it. Any chance that the CRAN machine that builds the aarch64 binary package links against some other version of freetype that pulls in the dependency?
