Log message:
Bump the PKGREVISIONs of all (638) packages that hardcode the locations
of Perl files to deal with the perl-5.8.7 update that moved all
pkgsrc-installed Perl files into the "vendor" directories.

Log message:
Turn PERL5_PACKLIST into a relative path instead of an absolute path.
These paths are now relative to PERL5_PACKLIST_DIR, which currently
defaults to ${PERL5_SITEARCH}.  There is no change to the binary
packages.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add RMD160 digests to the SHA1 ones.

Log message:
since perl is now built with threads on most platforms, the perl archlib
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.

Log message:
Initial import of p5-XML-RAI.

The RSS Abstraction Interface, or RAI (said "ray"), provides an
object-oriented interface to XML::RSS::Parser trees that abstracts
the user from handling namespaces, overlapping and alternate tag
mappings.

It's rather well known that, while popular, the RSS syntax is a
bit of a mess.

RAI provides a single simplified interface that maps one method
call to various overlapping and alternate tags used in RSS feeds.
The interface also abstracts developers from needing to deal with
namespaces. Method names are based on Dublin Core terminology.
