IIUC, this installs man pages and ‘COPYRIGHT’ to OUT/lib/erlang, right?
Shouldn’t it go to OUT/share/erlang instead?

Yes it does, and I found out that Erlang looks for man pages in
/gnu/store/.....erlang../lib/erlang/man

This can be verified by the output of running "erl -man -w"

You are right it seems a bit odd, but to my understanding that is just how
it is :)
