	In case it's relevant: I already have
	llvm-devel-2.8.r103179_1 installed.

>Description:
	After reading news of support for GCD on the mailing
	lists, I followed Robert's instructions here:
	http://wiki.freebsd.org/GCD
	and fetched up here:

libtool: link: clang -shared  .libs/libdispatch_la-apply.o .libs/libdispatch_la-benchmark.o .libs/libdispatch_la-object.o .libs/libdispatch_la-once.o .libs/libdispatch_la-queue.o .libs/libdispatch_la-queue_kevent.o .libs/libdispatch_la-semaphore.o .libs/libdispatch_la-source.o .libs/libdispatch_la-source_kevent.o .libs/libdispatch_la-time.o  -Wl,--whole-archive ./.libs/libshims.a -Wl,--no-whole-archive  -L/usr/local/lib -lpthread -lBlocksRuntime    -Wl,-soname -Wl,libdispatch.so.0 -o .libs/libdispatch.so.0
/usr/local/bin/ld: error in /usr/lib/crtendS.o(.eh_frame); no .eh_frame_hdr table will be created.
/usr/local/bin/ld: .libs/libdispatch_la-apply.o: relocation R_X86_64_PC32 against symbol `_dispatch_hw_config' can not be used when making a shared object; recompile with -fPIC
/usr/local/bin/ld: final link failed: Bad value
clang: error: linker command failed with exit code 1 (use -v to see invocation)
*** Error code 1

Stop in /nb/ports/devel/libdispatch/work/libdispatch-r174/src.

	I've encountered that R_X86_64_PC32 linker error before,
	but can't remember how it was resolved...

>How-To-Repeat:
	cd ports/devel/libdispatch; sudo make

>Fix:

	No idea, yet.  Looking into it.
