No; the "-perl5_12" is what I meant, since otherwise it will try to build
"+perl5_12 +perl5_14" and the two conflict.

And does this command does upgrade the all the ports that were compiled for

That's what the -R does, yes.  Although it may not catch *all* of them, as
some ports depend explicitly on perl5.12 instead of on perl5 --- nothing
can be done about these unless they have their own way to specify (and
sometimes they don't, because they simply aren;t compatible with other
versions).
