[105373] trunk/dports/lang/perl5.12

[Derek Harland]

Hi Josh,

* Background
  - I am currently building (in a separate tree) various ports linked against libc++ rather than libstdc++.  I am doing this by altering the portconfigure.tcl to add eg -stdlib=libc++ to configure.ldflags.

* Before this change, when perl is built it redefines ld as

    env MACOSX_DEPLOYMENT_TARGET =10.3 ${ld}

* There was already an existing patch which alters this command for darwin 9/10 to set MACOSX_DEPLOYMENT_TARGET properly.  I've simply extended it to darwin 11/12.

* I can't tell you the exact error without rebuilding, but without this patch the link fails on Lion saying something like ... "You're on 10.3, I can't support libc++ on 10.3, go away"

derek.
