Log message:
KERN_PROC_PATHNAME is slightly different on NetBSD vs FreeBSD; handle this
difference correctly.  Bump package revision to 1.

Log message:
On Darwin, add gsed to USE_TOOLS and patch the icestorm Makefile to
stop working around a behavioral difference in the Darwin sed(1) -i
option relative to other sed implementations.

If textproc/nbsed supported the -i option, the USE_TOOLS change would
not be necessary.  But since the Darwin system sed(1) is not used in
pkgsrc at the moment, the Makefile patch would still be required.
