 Build of libvpx fails as part of a complete rebuild of all installed ports
 after upgrade to OS X 10.7.3 (Lion) and Xcode 4.3.1. Prior to it failing
 the upgrade had successfully built other ports for about 7.5 hours. Also
 fails as part of a specific build just of libvpx.

 It's possible that the problem is missing include paths on the clang
 command.

 I'm using:[[BR]]
 OS X 10.7.3[[BR]]
 MacPorts 2.0.4[[BR]]
 Xcode 4.3.1

 Here's what I did:

 {{{
 sudo port selfupdate
 xcodebuild -license
 sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
 sudo port upgrade outdated
 }}}

 The build failed with:

 {{{

 --->  Configuring libvpx
 Error: Target org.macports.configure returned: configure failure: shell
 command failed (see log for details)
 Log for libvpx is at:
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_multimedia_libvpx/libvpx/main.log

 }}}

 Checking main.log (attached) I found:

 If you

 is to look

 what

 I added /usr/include to the include path and the compile was successful:

 {{{
 $ cat >/tmp/my_test.c#include "stdio.h"int x;
 $ /usr/bin/clang -I /usr/include -O2 -arch x86_64 -isysroot -mmacosx-
 version-min=10.7 -m64 -fomit-frame-pointer -arch x86_64 -O3 -fPIC -E -o
 /tmp/my_test.o /tmp/my_test.c
 $
 }}}

 So, how do I fix this and get the build to proceed?

 [Note, {{{port list libvpx}}} showed the Maintainers as
 nomaintainer at macports.org, so I've cc'd this there; sorry if that's the
 wrong thing to do]
