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.

Its possible to accidentally inherit an AUTOLOAD method. Often this
will happen if a class somewhere in the chain uses AutoLoader or
defines one of their own. This can lead to confusing error messages
when method lookups fail.
Sometimes you want to avoid this accidental inheritance. In that
case, inherit from Class::WhiteHole. All unhandled methods will
produce normal Perl error messages.
