module directory has changed (eg. "darwin-2level" vs.
"darwin-thread-multi-2level").
binary packages of perl modules need to be distinguishable between
being built against threaded perl and unthreaded perl, so bump the
PKGREVISION of all perl module packages and introduce
BUILDLINK_RECOMMENDED for perl as perl>=5.8.5nb5 so the correct
dependencies are registered and the binary packages are distinct.

The Perl module Digest::BubbleBabble can be used to create a fingerprint of
a MD5 or SHA-1 digest in "bubble babble" format. Bubble babble is a method
of representing a message digest as a string of "real" words, to make the
fingerprint easier to remember. The "words" are not necessarily real words,
but they look more like words than a string of hex characters.
