 > [wiki:XcodeVersionInfo#OSX10.7 Xcode 4.6.3 is indeed] the latest version
 you can use on Lion, however Apple clang version 2.1 a.k.a clang-163.7.1
 does not correspond to that version of Xcode; it corresponds to
 [wiki:XcodeVersionInfo#MacOSX10.6 Xcode 4.1]. Please upgrade your clang by
 installing "Command Line Tools (OS X Lion) for Xcode - April 2013" which
 you can get at the [https://developer.apple.com/downloads/ Apple Developer
 Downloads] page after logging in, or via the Downloads section of the
 Xcode application's Preferences window.
 Thanks for the precise instructions. I upgraded to the newer command line
 tools, my clang version is now Apple LLVM version 4.2 (clang-425.0.28)
 (based on LLVM 3.2svn). I then uninstalled the patched version of
 pkgconfig, and installed it again from fresh, this time without a hitch.
 Thanks for your help, and sorry for being unaware of the too old command
 line tools problem.

 index.netbsd.org/pkgsrc-bugs/2013/10/16/msg052707.html Perhaps it only
 affects older versions of clang, such as we would find on Lion.

 > Thanks for verifying that. It looks like even the current version of
 glib does not include such a change. However current compilers merely
 consider this condition a warning, not an error as your old version of
 clang does. I will try to find out if this problem was ever reported to
 the developers of glib, and if so, what their response was.
