Latest update to math/py-numeric fails in "make patch" due to
	mismatch between ${PORTNAME} and the extracted ${WRKSRC} 
	directory's name.

	Actually, there are two problems here:

	1) The source distfile doesn't extract to the default of 
	${WRKDIR}/${PORTNAME}-${PORTVERSION}, the difference being that
	the extracted ${WRKSRC} name is capitalized, while the port's name 
	is not.

	2) The extra (doc) distfile "numpy.pdf" is first being copied to
	${WRKSRC} in the post-extract target, but then the post-install 
	target tries to install it from ${WRKDIR} instead, resulting in a 
	"No such file or directory" error.

Fix: Diff attached below to correct both of the aforementioned problems
	in the port's Makefile.  There are, of course, two possible 
	solutions to problem (2) above: either adjust the post-extract 
	target to copy the PDF file to ${WRKDIR} instead of ${WRKSRC}, or 
	adjust the post-install target to install the file from ${WRKSRC} 
	instead of ${WRKDIR}.  In the patch below, I opted for the first 
	solution.
How-To-Repeat: 	cd ${PORTSDIR}/math/py-numeric; make install
