I've certainly had little trouble with XML::FOAF or RDF::Core just now. 
I also don't have Crypt::OpenPGP and yet it seems to work just fine.

My FOAF data source is actually the simplest of the bunch, since this 
module does all of the work:

     my $doc = new XML::FOAF(\$content, $url);
     my $p = $doc->person();

     my $ret = {
         'name' => $p->name(),
         'nick' => $p->nick(),
         'mbox_sha1' => $p->mbox_sha1sum(),
         'website_url' => $p->homepage(),
         'weblog_url' => $p->weblog(),
         'photo' => $p->img(),

(that's not actually all of it, as there are a few special cases below 
and some error handling. Still much simpler than my code to handle Atom, 

It seems to work reliably for every FOAF file I've tried, too. That's 
more than I can say for RSS and Atom! To be fair, though, neither of 
those formats are designed for this purpose so I shouldn't be so hard on
