rrdtool: generating perl lib only for 5.12, depending ports need to adjust

[jul_bsd@…]

$ port contents rrdtool|grep RRDs.pm
  /opt/local/lib/perl5/vendor_perl/5.12.4/darwin-thread-multi-2level/RRDs.pm

as a result, other port should also be restricted to the same perl version like argus-clients (ragraph which by default executes w 5.16).

$ ragraph

if possible add variant to each perl release?

Thanks

rrdtool does not specify which version of perl to use; this is a bug. And since apparently the modules installed by the rrdtool port are used by other ports, those modules should be split out into a p5-rrdtool port or similar, so that subports can exist for each supported version of perl.

[jul_bsd@…]

I added variants inside the port.

any blocking points?

update to 1.4.8; add variant for perl 5.20

[mf2k (Frank Schima)]

markd has retired. See #44782.

[dbevans (David B. Evans)]

As of r129018, rrdtool now uses perl 5.16. Since we are actively trying to actively remove (or at least reduce) support for multiple perl versions, perl variants are not added at this time.

[jul_bsd@…]

Ok but why perl 5.16 vs 5.18 or 5.20?

[dbevans (David B. Evans)]

Because 5.16 is the current default for port perl5. All (non p5*) ports now depend on perl5.16 including ports that depend on rrdtool.
