mrtg-2.16.2_6,1 does not run with perl-5.12.1_1

[Jon Theil Nielsen]

Hi list

After upgrading perl according to UPDATING, I cannot use mrtg anymore. The
error message is:

Bareword "P_DETACH" not allowed while "strict subs" in use at
/usr/local/lib/perl5/site_perl/5.12.1/MRTG_lib.pm line 1172.
Compilation failed in require at /usr/local/bin/mrtg line 89.
BEGIN failed--compilation aborted at /usr/local/bin/mrtg line 89.

I filled a PR on this but haven't seen any answers/solutions:
http://www.freebsd.org/cgi/query-pr.cgi?pr=148914

Am I the only one having this problem?

If the port needs upgrading (as suggested in my PR), but this does not
happen, how can I fix it myself?

Cheers,
Jon
