>Description:
	The current bsd.port.mk has some poorly worded scripts, which
	the patch below speeds up. In particular, all invocations of ${CUT}
	are eliminated, and pipes with more than one instance of tr, cut,
	grep, awk, or sed are compacted.

	In the case of x11/kde3 the changes make ``make missing'' or
	``make package-depends-list'' finish over 10% faster --
	mostly due to reduction of the sys-time, since much fewer
	external sed/cut/tr processes need to be spawned.

	The patch also avoid redundant sub-shells in a couple of places,
	and somewhat unifies accessing data in the MD5_FILE.

	Lastly, it makes the uninstall try to remove bzip2-ed man-pages
	in addition to gzip-ed ones.
