Is there a reason to not use source tarball from https://github.com/opencollab/jlatexmath ?
(In reply to Max Brazhnikov from comment #2)
But tarball wouldn't make any difference, because the distfile is an archive of the maven cache pre-built locally. USE_GITHUB/GH_ACCOUNT are there only for convenience during port updates.
