things that I am having trouble building

[Greg Troxel <gdt%lexort.com@localhost>]

As usual I am doing pkg_rr on a number of systems, which are basically
up to date on their netbsd branch and using today's pkgsrc head.  For
netbsd-7 i386, a lot of things are failing, and I'm trying to only list
the breaking packages.

netbsd-7 i386:
