The problem is more serious. Perl6 installation needs to have multiple

Why?
Because we need things to work effectively in the general case where what was
originally a single module Foo with one name becomes forked with each creator
(authority) going off in their own direction, or alternately the creator makes
incompatible changes, and then later someone's project Bar may have a bunch of
dependencies A and B where A depends on one version of Foo and B depends on an
incompatible version of Foo; then both versions of Foo need to work together.
And that's just one reason to have this support. -- Darren Duncan
