Comment (by mtb19@…):

 For version 3.3, the offending chown command can be found on line 38 of
 the libcxx/Makefile:


 {{{
       1 ##
       2 # libcpp Makefile
       3 ##
       4
       ...
      32
      33 # The installheaders target is used by clang's runtime/libcxx
 makefile.
      34 installheaders::
      35         mkdir -p $(HEADER_DIR)/c++/v1/ext
      36         rsync -r --exclude=".*" --exclude="support"
 $(SRCDIRS)/include/* \
      37           $(HEADER_DIR)/c++/v1/
      38   >>>>  chown -R root:wheel $(HEADER_DIR)/c++  <<<<
      39         chmod 755 $(HEADER_DIR)/c++/v1
      40         chmod 644 $(HEADER_DIR)/c++/v1/*
      41         chmod 755 $(HEADER_DIR)/c++/v1/ext
      42         chmod 644 $(HEADER_DIR)/c++/v1/ext/*
      43
       ...
 }}}

 When I commented out line 38 in
 /__PATH__/var/macports/build/___PATH___var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_llvm-3.3/clang-3.3/work/trunk/projects/libcxx/Makefile,
 my build completed without issue.

 I do not know enough about port files to know how to apply a patch
 conditioned on a non-root install. I'm hoping the above info makes it easy
 for someone with more expertise....
