While trying to install Digest::BLAKE2 sudo -S cpan install Digest::BLAKE2

I got the following error:

This package is a dependency of the PET pipeline.

You can patch a local version of Digest::BLAKE2 that can be installed locally, the fix is quite minor, and is detailed here: https://github.com/Raptor3um/raptoreum/issues/48#issuecomment-969125200

effectively all lines that begin with ALIGNME( 64 ) in blake2.h need ALIGNME(64) moved to the middle of the line, e.g. typedef struct ALIGNME( 64 ) __blake2s_state

i've attached the a tar.gz of the patch i made by making the above change throughout in case it is helpful. it installs in ubuntu 22 and 24 docker containers using cpanm. Digest-BLAKE2-0.02.tar.gz
