Upgrading perl

[Jack Stone]

uname -a FreeBSD mail.sagedata.net 7.0-RELEASE-p9 FreeBSD 
7.0-RELEASE-p9 #2: Sun Jan 18 19:59:27 CST 2009

Running perl5.10 (yeah, old!)
This is a production server.


Been playing catchup on ports including perl as UPDATING recommends:
portupgrade -o lang/perl5.12 -f perl-5.10.\*

That has worked on other servers, but not this one. Anyone know what I 
need to do to clean this up??

But, can't get past this fatal error:
mail# portupgrade -o lang/perl5.12 -f perl-5.10.\*
"/usr/ports/Mk/bsd.options.mk", line 231: Error in archive 
specification: "WITHOUT_"
