NetBSD 8.2 Package refresh fails

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hi!

I am pursuing the build  through pkg_rolling-replace on 8.2 all packages 
that did not update from 7 due to them being missing on the repository 
or anyway needed update.

Worked around the OpenSSL issue, things compiled for days. ICU is a "bad 
boy" since it does not use 2 CPUs essentially and instead other packages 
instead suck a lot of RAM... anyway.

Pango stopped for me, this error:
