p90 [1] filed a deletion request for icecube-pal-git [2]: This package was based on a fork used by the IceCube colloboration. The fork is now unmaintained, including issues which make running it on modern Arch impossible without patches (which the fork does not want)
The recommendation is to directly use the starlink/pal which already has a package. [1] https://aur.archlinux.org/account/p90/ [2] https://aur.archlinux.org/pkgbase/icecube-pal-git/
