> While I’m all for getting perl 5.20 up to speed on Macports, I’m against removing perl 5.16 or perl 5.18. I have been testing a number of p5 ports with perl 5.18 and only 1 of them failed to build for me. But it is an important one. The port is p5(.18)-pdl and it is needed for the demeter/demeter-devel ports.

PDL appears to build fine with perl 5.20

I just built it against my perlbrew-managed perl5.20 on Mac OS X 10.9 and it passed its test suite [I didn't install all of the optional dependencies - one or more of which likely are causing the build problem(s) you're seeing].

which would be fixed by reverting the previous change (installing stuff in to 5.20.x/ by default instead of 5.20/) - which was in itself an attempt to make #5 less necessary.

> I think it is way too early to be switching to it by default. Much less the only option. So I vote we at least keep perl 5.16 and perl 5.18 and all of their modules around for a while.  

only perl5.18 currently has a maintainer in MacPorts.

upstream has perl5.18 in maintenance mode, and recommends installing perl5.20 (previous perl5.x versions are all End of life).
