devel/libc++ too old

[clutton]

Hi list.

I was scared to write here for a long time. Now it's probably the time
to deal with my fears :)

New www/chromium port (currently only on github) has problems building
on 10.1 and 9x releases because of outdated libc++. I tried to use
libc++ from ports and just has found that the library is outdated too.
It gave me an error from clang 3.6 time if I'm not mistaken. Are there
any plans to update the port?

Also, thank you for maintaining such huge and great toolkit.
