Something is wrong:

on NetBSD/sparc64 running -current, with -current pkgsrc as of 2 days ago
(or so), I get:

===> Creating toolchain wrappers for ffmpeg4-4.3.1nb4
ERROR: libdrm>=2.4.15 is not installed; can't buildlink files.

This is a ... suboptimal error message, and it is not obvious to me how
the pkg gets anywhere near libdrm at all.

Besides, it always used to work on sparc64, so someone must have broken
something ;-)

Any hints?
