Perl ports problem

[Roger Merritt]

I don't know if this is really a ports problem, but I'm more familiar with 
these lists so decided to ask here first.

I was trying to install a Content Management System (MkDoc) which requires 
several perl ports. Many of the ports installed with no problem, but now 
I've run into several that all seem to have the same header file missing:

Other ports are p5-Unicode-String and p5-Unicode-MapUTF8 which both also 
fail for lack of /usr/libdata/perl/5.00503/mach/CORE/opnames.h. I 
re-cvsup'ed the ports tree and deleted the tar files from 
/usr/ports/distfiles, but even downloading the tarball fresh didn't help. 
Is this a perl/CPAN issue?
