It seems to me that the problem with 10.10 has been fixed, but the
 following chunk of code seems problematic and I need some help with it:
{{{
my $tools43 = '/Applications/Xcode.app/Contents/Developer/Tools';
my $restoolpath = ( -d $tools43 ) ? $tools43 : '/Developer/Tools';
This is just setting $restoolpath to whichever of these two paths exist as
 a directory.  These are the expected installation paths for Xcode in a
 standard default install.  /Developer/Tools was used in older version, new
 versions (4.3 on I'm guessing based on the variable name) use
 /Applications/Xcode.app/Contents/Developer/Tools.  This won't work if you
 have placed Xcode in a non-standard location.  However, using /usr/bin
 will only work if xcode-select has been properly set to link to your
 install location.  I think it would be better to figure a way to find the
 absolute path to the proper directory.  Normally MacPorts does this for
 you.
...
sub get_flags {
  my $this = shift;
  my %config = $this->SUPER::get_flags;
I think the code enclosed in the if statement following can just be
 removed.  It's trying to fixup $config{CC} and $config{LD} for each of the
 listed versions assuming your using a vanilla install of perl.  Our perl
 versions set these config values correctly so nothing to do here -- just
 return %config.

 Try the following to see values of these flags (The example was run on
 Mavericks)

 {{{
 $ perl5.16 -V:cc -V:ld
 cc='/usr/bin/clang';
 ld='env MACOSX_DEPLOYMENT_TARGET=10.9 /usr/bin/clang';
 }}}

 Remove this:
...
if ($config{CC} =~ /clang\+\+/ || $config{LD} =~ /clang\+\+/) {
      my $sdkrepl = '';
      for my $sdkversion ( qw( 10.9 10.8 10.7 10.6 ) ) {
        my $macossdk =
 qq(/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX${sdkversion}.sdk);
        if( -d $macossdk ) {
              $sdkrepl = 'clang++ -isysroot ' . $macossdk . '
 -stdlib=libc++';
              last;
        }
      }
      if ( $sdkrepl ) {
        $config{CC} =~ s/clang\+\+/$sdkrepl/g;
        $config{LD} =~ s/clang\+\+/$sdkrepl/g;
      }
  }
Keep this
...
return %config;
}
}}}
First of all there is absolutely no guarantee that users installed Xcode
 under `/Applications/Xcode.app/Contents/Developer/Tools` (I didn't). My
 workaround so far was to set
{{{
my $restoolpath = '/usr/bin';
}}}
But I don't understand the rest of the code either. Is it trying to
 force `libc++` on 10.6, where setting `-isysroot /path/to/sdk` will make
 sure that it won't work??? And why does it only list 10.6 - 10.9?
See above.
