joseasoler [1] filed an orphan request for trng4-git [2]: This package no longer builds because upstream has switched to CMake but the PKGBUILD has not been updated. The package was flagged as out- of-date a long time ago. I made an attempt to contact the maintainer by commenting in the package, but I did not get a response.
