perl tests failing in sparc64 netbsd-6

  With pkgsrc-2012Q1, perl-5.14.2, running on a netbsd-6 sparc64, I see a number of failures from "make test":

Failed 30 tests out of 2016, 98.51% okay.

  Now, as perl tests go, those aren't *lots* of failures, but really, it's been a long time since I've seen that many failures, and at least one of them caused a SEGV on the perl test run.

  Does anyone have any idea if this is normal and/or expected, or if it's an indication of some sort of problem with either the pkgsrc perl I've built, or the system as a whole?

  Thanks...
