New description:

 I'm seeing the following errors when installing TexShop3 on my Mac laptop:
 {{{
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_aqua_TeXShop3/TeXShop3/work/texshopsource388/Sources/TSDocument.m:1793:17:
 error: 'release' is unavailable: not available in automatic reference
 counting mode
                 dispatch_release(dispatch_source);
 }}}
 (This error is repeated twice).

 I have attached the verbose log generated by port -v install TexShop3.
