Comment:

 Committed in r117656 with these changes:

  * adjust whitespace to conform to modeline (indents at multiples of 4
 spaces)
  * use github portgroup
  * download distfile from homepage, since that's where the download link
 takes you, and because those are bz2 files, which are smaller than the gz
 files github offers
  * patch Makefile to remove incorrect assumptions about where it should
 look for dependencies
  * ensure we're UsingTheRightCompiler and `-arch` flags
  * add universal variant and set `ARFLAGS` in order to add the `s` flag
 which makes the universal build succeed; equivalently, we could have
 patched lib/Makefile to run `ranlib` after running `ar`
  * use destroot.env instead of destroot.post_args, thereby eliminating the
 need to specify destroot.destdir again
  * all build environment variables needed to be copied to the destroot, so
 I used `eval` to accomplish that
  * add dependency on zlib, since the Makefile does use the flag `-lz`
  * [PortfileRecipes#doc install documentation files]
