ports/64027: [Maintainer] lang/pnet* -- add PORTDOCS and missing lib for X support.

[Michael Johnson]

actually, I don't know what I was thinking about BUILD_DEPENDS vs. 
LIB_DEPENDS
in lang/pnet/Makefile for pnet uses X* libs and headers to compile

please change the following from my patch in lang/pnet/Makefile

.if !defined(NO_X)
-RUN_DEPENDS+=   ${X11BASE}/lib/libXext.so.6:${PORTSDIR}/x11/libXext
+LIB_DEPENDS+=   Xext.6:${PORTSDIR}/x11/libXext
.endif

and add the following to lang/pnet-base/Makefile

.if !defined(NO_X)
LIB_DEPENDS+=   Xext.6:${PORTSDIR}/x11/libXext
.endif
