>Description:

	pkgsrc providesa "PKGSRC_LOCKTYPE" variable that i've had set
	to "sleep" ever since it was introduced.

	there seems to be new targets that are not under this lock and
	concurrent builds can stomp on each other.  i've seen this
	failure while attempting to both create or install a binary
	package using "make package-install".

	eg, one window shows:

=> Automatic manual page handling
=> Creating binary package /var/obj/pkgsrc/devel/cmake/work.phat-bass/.packages/cmake-3.0.2.tgz
mv: rename /var/obj/pkgsrc/devel/cmake/work.phat-bass/.packages/cmake-3.0.2.tmp.tgz to /var/obj/pkgsrc/devel/cmake/work.phat-bass/.packages/cmake-3.0.2.tgz: No such file or directory
*** Error code 1

Stop.
make[3]: stopped in /usr/pkgsrc/devel/cmake


	and in another window:

===> Install binary package of cmake-3.0.2
pkg_add: Failed to read from archive for cmake-3.0.2: Damaged tar archive
original MD5 checksum failed, not deleting: /usr/pkg/bin/cpack
[ ... ]

>How-To-Repeat:

	"make package-install" in two subdirs with a common dependancy
	target.  one or both of them may fail after the package is built
	but before it is packaged or installed.
