Well, configure looks for libxml2 by running xml2-config, not pkg-config. (Check the use of PKG_CHECK_MODULES_MACHACK , from acinclude.m4.)

And at least on 10.6.7 with Xcode3 *and* Xcode4 installed, there is a /usr/bin/xml2-config, which gets used, and not the one that would correspond to the SDK we want to build with, which at least for me also comes with an xml2-config, in /Developer/SDKs/MacOSX10.4u.sdk/usr/bin/xml2-config .

Not that things would be all good if /Developer/SDKs/MacOSX10.4u.sdk/usr/bin/xml2-config --cflags was run instead either; for some obscure reason that *still* outputs -I/usr/include/libxml2, instead of what it presumably actually means, -I/Developer/SDKs/MacOSX10.4u.sdk/usr/include/libxml2. Go figure. Seems like whoever ported libxml2 to the 10.4 SDK didn't bother making the xml2-config script actually adapt to where the 10.4 SDK is installed, but it hardcodes the installation location -relative /usr path as if it was absolute. Or whatever.

And still another point is that we hardcode this /Developer/SDKs/MacOSX10.4u.sdk path a couple of times in the configure.in, but surely that software package can be installed in some other location, too... Is there any way to find out the actual installation root of the 10.4 SDK?
