External `hadrian` fails on ghc installation

I am working on switching ghc on Gentoo Linux to the new hadrian system. Instead of using ./hadrian/build, which requires cabal-install, I have extracted hadrian from the ghc sources and made it into it's own package. This is installed on my system and hadrian lives in /usr/bin/.

I am currently testing this approach with ghc-9.2.6, but I cannot seem to get past this error, which happens after a successful build when I try to get hadrian to install ghc:

>>> Install dev-lang/ghc-9.2.6 into /var/tmp/portage/dev-lang/ghc-9.2.6/image
