PlasticSoup [1] filed a deletion request for elmer [2]: Package fails to build, PKGBUILD uses git:// instead of git+https://. This is a VCS package despite release versions existing. Upstream URL points to a different project than what would be built if this PKGBUILD worked. So the target code would need to be under a package named elmer-old-git. The new elmer project has no releases, so it would need to be elmer-git. Upstream has not been active in over 8 years.
