clang 3.4 can't be configured (part of a selfupdate)

[Ken Cunningham]

Oh - it's arch x86_64, by the way... late night brain fart.]

More I look at the different issues you have going on here, more I think what I would do is just start over. It's time consuming, but 100% reliable.


I'd delete these three files:

-rwxr-xr-x  1 root  wheel  1186580 12 Jan  2016 libc++.1.dylib
lrwxr-xr-x  1 root  wheel       14 28 Jul 20:36 libc++.dylib -> libc++.1.dylib
-rwxr-xr-x  1 root  wheel   431040 24 Nov  2015 libc++abi.dylib

Move your opt folder out of the way

sudo mv  /opt /opt-junked

reinstall macports from the package

do a sudo port selfupdate (I think it happens anyway when you install).

And then go straight to the libcxxOnOlderSystems page and follow the instructions line by line before you do anything else.


=============

if that's just not acceptable, I'd uninstall all traces of clang, llvm, ld64, and cctools until there is nothing left when you search for these ports, reset your macports.conf and variants.conf to the default settings, delete the /usr/lib files listed above, and follow the instructions carefully. 

Hope this helps.
