Build of inkscape-0.48.x r10017 fails when building in MacPorts using recently released Xcode 5.1. This effects both OS X 10.8 (Mountain Lion) and 10.9 (Mavericks). Build is successful using previous version Xcode 5.0.2.
Build of trunk (r13156) and standalone lib2geom (r10017) are not effected.
Fails as follow:

Compiler info:
clang: Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
<https://trac.macports.org/wiki/XcodeVersionInfo#OSX10.9>
As pointed out the difference between Xcode 5.0.2 and Xcode 5.1 is that clang is now based on LLVM 3.4 rather than LLVM 3.3. It's possible that this failure could effect other platforms using clang 3.4 although I haven't tried it.
