FabioLolix [1] filed a deletion request for nupack4 [2]: One time effort on 2022-09-07, abandoned, depends on tbb2019 that don't exist in any form for 2+ years now
The program is source available behind registration and a real hassle to package; selected comments from former packager: "Maintaining this package is not practically sustainable, given the complicated build process seemingly not intended for others, the frequent dependencies and dependency changes on specific and outdated versions of libraries, compilers and build tools, and the difficult licensing situation. As was the case with the 4.0.0.28 version here, an updated PKGBUILD would also likely require installation of numerous outdated dependencies conflicting with many other packages." "The PKGBUILD here would work for 4.0.0.28 (if tbb2019 were still availiable), but updating to 4.0.2.0 seems like it would require extensive changes; the process appears to be incompatible with cmake 14, with recent clang, and with current versions of a number of new dependencies, and also appears to have some new dependencies not available in AUR."
