configure not finding fontconfig on OSX

[Richard Campbell]

I did a find /usr | grep -i fontconfig and it returns, in part:

/usr/X11/include/fontconfig
/usr/X11/include/fontconfig/fcfreetype.h
/usr/X11/include/fontconfig/fcprivate.h
/usr/X11/include/fontconfig/fontconfig.h
/usr/X11/lib/libfontconfig.1.4.3.dylib
/usr/X11/lib/libfontconfig.1.dylib
/usr/X11/lib/libfontconfig.dylib
/usr/X11/lib/pkgconfig/fontconfig.pc
/usr/X11/lib/X11/fontconfig
/usr/X11/lib/X11/fontconfig/conf.avail
/usr/X11/lib/X11/fontconfig/conf.avail/05-osx-fonts.conf
/usr/X11/lib/X11/fontconfig/conf.avail/10-autohint.conf
...

When I do ./configure --disable-docs, the relevant parts of the output are:



checking for freetype-config... /usr/X11/bin/freetype-config
checking for FreeType -- version >= 9.0.3... yes
checking for FONTCONFIG... checking for fltk-config... no
...

When I invoke cpp -v I get:

#include <...> search starts here:
 /Developer/usr/bin/../lib/gcc/i686-apple-darwin10/4.2.1/include
 /usr/local/include
 /usr/lib/gcc/i686-apple-darwin10/4.2.1/include
 /usr/include
 /System/Library/Frameworks (framework directory)
 /Library/Frameworks (framework directory)


So why is it finding freetype but not fontconfig? Neither are in the search 
paths, so I'm surprised it's finding freetype. I've tried defining CFLAGS and 
CXXFLAGS with -I/usr/X11/include and it doesn't seem to have an effect.
