Hello, It seems that guile2.2 is built by make-bootstrap.scm here: https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/make-bootstrap.scm?h=core-updates#n625 but guile2.0 is expected here: https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/bootstrap.scm?h=core-updates#n373 For the purpose of my ongoing port to powerpc64le-linux-gnu, I applied the attached patch, but obviously that one wont work with the previously built tarballs for x86_64 etc. Things would have to be split in parts somehow, for old bootstraps with version 2.0 and newer ones with version 2.2. Thanks
