问题
In an effort to
sudo port install gcc47
It appears that i am missing
- cctools
- ld64
- libunwind-headers
where both
- cctools
- ld64
depend on
- libunwind-headers
When trying to
sudo port install libunwind-headers
I get:
---> Building libunwind-headers
Error: org.macports.build for port libunwind-headers returned: command execution failed
Please see the log file for port libunwind-headers for details:

You need to accept Apple's license agreement before attempting to install libunwind-headers
sudo xcodebuild -license agree
