Fix rakudo not finding the souce of a dependency in a non-standard repo
Fix rakudo not finding the souce of a dependency in a non-standard repo

Paths to souce files must either be relative to a named repository as
in: perl6#sources/123456789ABCDEF or absolute as in /tmp/foo/1234567...

Should fix issues with make DESTDIR=/foo/bar install
