Why does the log say

:debug:configure Using compiler 'System cc'

? It should say it's using clang. When the compiler is clang, the portfile removes the -Werror flag that's causing your build failure.

I have no idea, I didn't pass any options to install, so this is all default.

Anything else I can do to help?

I've worked around the problem in r112927 but we still need to understand why your compiler isn't being set to the correct default value.

Have you installed Xcode 5.0.1, and installed the command line tools by running xcode-select --install?

I've tried it on another machine and I could build 1.4.14. This machine has Xcode installed.

The other non-working has only Xcode Cli Tools installed.

[ryandesign (Ryan Carsten Schmidt)]

Both Xcode and the command line tools are required for MacPorts.
