I've used an old "lite" version and am looking to expand my use of LibRAW. In the end, I'll want to try to get things compiled up as a Universal Binary for 10.4+ and on Windows, but for now, I'm just looking to get things up and going. I'm on OS X version 10.6.7 and XCode version 3.2.2. Since you've got it compiling on OS X already, this is likely due to different XCode versions or a brain lapse on my part. But, here's what I'm getting:

./configure

checking for a thread-safe mkdir -p... ./install-sh -c -d

----------

Note, I do get further in configure with:

arch_flags=-isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.4

./configure CFLAGS="$arch_flags" CXXFLAGS="$arch_flags" LDFLAGS="$arch_flags" OBJCFLAGS="$arch_flags" OBJCXXFLAGS="$arch_flags"
...

checking how to run the C preprocessor... /lib/cpp
configure: error: in `/Users/stark/dev/LibRaw-0.13.5':
configure: error: C preprocessor "/lib/cpp" fails sanity check

Any thoughts?
