That's a good fix.  The only issue is upgrading ikiwiki, since new
versions of search.pm will overwrite this change.  The plugin is located
at:

    /usr/pkg/lib/perl5/vendor_perl/5.10.0/IkiWiki/Plugin/search.pm

So if our changed version goes in any of:

    /usr/pkg/lib/perl5/site_perl/5.10.0/i386-dragonfly-thread-multi
    /usr/pkg/lib/perl5/site_perl/5.10.0
    /usr/pkg/lib/perl5/vendor_perl/5.10.0/i386-dragonfly-thread-multi

(from perl -V) It should get picked up first, I think.  There's a slightly
newer version of ikiwiki that should be installed first, though, as
there's been a few quick minor releases.  If I can't get it upgraded
tonight, I'll get it done this weekend.
