--------------------------------------------+------------------------------
 on Lion (Mac OS X 10.7.5) i see a problem doing "port -v install
 handbrake". Extracting the relevant failure details from the log.
 I have XCode 4.6 installed and am using the command line tools that come
 with it.

 First, the command that shows the problem (redacted to be readable)

 Note that all paths have
 `local/var/macports/build/_opt_local_var_macports_sources_mse.uk.rsync.macports.org_rsync.macports.org_release_tarballs_ports_aqua_HandBrake/HandBrake/work`
 removed

 we see the -lass that is referring to the `libass.a` made by HandBrake in
 the contribs/lib subdirectory.

 the resulting error is
 {{{
 Undefined symbols for architecture x86_64:
   "_hb_buffer_add_utf32", referenced from:
       _shape_harfbuzz in libass.a(ass_shaper.o)
   "_hb_buffer_create", referenced from:
       _shape_harfbuzz in libass.a(ass_shaper.o)
 ...
 }}}
 I show only 2 of the 20+ undefined symbols in the list, seemingly all from
 ass_shaper.o

 the final msg is
 {{{
 ld: symbol(s) not found for architecture x86_64
 clang: error: linker command failed with exit code 1 (use -v to see
 invocation)
 }}}

 thinking that libass.a might be the one in /opt/local/lib, which comes in
 with ffmpeg, I thought to remove it by uninstalling ffmpeg
 @2.2.2_1+gpl2+nofree

 the HandBrake build failed at the same place.

 I tried drilling down to the libass directory and doing `make clean`and
 then `make`to see if that would give any insight as to how the library was
 built. The following build of HandBrake failed in the same way.

 Then I cleaned HB out again and tried it from scratch to be able to give
 you a clean log file.

 attached are 2 text files, the captured scroll back from the terminal
 session and the main log file
