MarsSeed [1] filed a deletion request for gl2ps-svn [2]: Defunct, improper VCS package from 2016, uses a tar.gz instead of a Subversion repository. The source is also gone (404 not found).
In 2018, a user mentioned that upstream has migrated to Git, and submitted a working PKGBUILD for that. But owner ignored it. This package should be deleted. Users have access to extra repo's working gl2ps build. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gl2ps-svn/
