Yepp - same here.
I am currently trying to re-build meta-pkgs/kde3 within pkg_chroot
with yesterdays -current system and X. 
To make Xrender work for pango (and some things more) try following:

in: x11/Xrender/buildlink2.mk
after:
BUILDLINK_TARGETS+=             Xrender-buildlink

add:
BUILDLINK_TARGETS+=             Xrender-buildlink-la

Xrender-buildlink-la:
        ${_PKG_SILENT}${_PKG_DEBUG}                                     \
        lafile="${BUILDLINK_DIR}/lib/libXrender.la";                    \
        libpattern="${BUILDLINK_PREFIX.Xrender}/lib/libXrender.*";      \
        ${BUILDLINK_FAKE_LA}

you may want to comment out BUILDLINK_FILES.Xrender+=      include/X11/extensions/region.h

Then pango should build after a make clean.

As for re-building kde3 I am currently stuck at:
] ...
] shlibtool: link: warning: `/pkg_comp/obj/pkgsrc/x11/kdebase3/work.i386/.buildlink/lib/libXrender.la' seems to be moved
] ... more moveds and then:
] grep: /usr/X11R6/lib/libXrender.la: No such file or directory
] sed: /usr/X11R6/lib/libXrender.la: No such file or directory
] shlibtool: link: `/usr/X11R6/lib/libXrender.la' is not a valid libtool archive

] make: stopped in /usr/pkgsrc/x11/kdebase3
] *** Error code 1
] 
] Stop.
] make: stopped in /usr/pkgsrc/x11/kdebase3
] 
Now I am stuck with finding out why /usr/pkg/bin/shlibtool thinks it
must dig around /usr/X11R6/lib for libXrender* which it already found
some time before ... 8-(
