 The error on 10.8 is
 {{{
 /opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_graphics_glfw/glfw/work/glfw-3.3.7/src/cocoa_window.m:328:46:

     if ([window->ns.object occlusionState] &
 NSWindowOcclusionStateVisible)
                                              ^
 }}}
 on 10.7:
 {{{
 /opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_graphics_glfw/glfw/work/glfw-3.3.7/src/cocoa_init.m:92:19:
 error: expected method to read dictionary element not found on object of
 type 'NSDictionary *'
         id name = bundleInfo[nameKeys[i]];
                   ^
 }}}
 These platforms might need to use an older version similar to what is done
 for 10.6.
