Description:
------------
I can't get php 5.1.2 to compile with gd and freetype2. I have 
tried using the bundled gd and also gd-2.0.33-3 from fink. 
I've also tried using freetype2-2.1.9-1 from fink and the 
system standard install at /usr/X11R6. Compiling without 
freetype (any version) results in a working (minus freetype 
features) gd extension.
I'm pretty sure I'm using correct paths, as mentioned in 
various places including this bug: http://bugs.php.net/
bug.php?id=27625.
I do not have this problem when compiling on Linux with 
similar settings.

Reproduce code:
---------------
my config.nice (cut down to just environment, gd and freetype related options):

CFLAGS='-DBIND_8_COMPAT=1 -DEAPI -O3 -mcpu=G4 -mtune=G4 -I/sw/include' \
CXXFLAGS='-I/sw/include' \
CPPFLAGS='-I/sw/include' \
LDFLAGS='-L/sw/lib' \
'./configure' \
'--with-layout=Darwin' \
'--bindir=/usr/bin' \
'--enable-gd-imgstrttf' \
'--enable-gd-native-ttf' \
'--sysconfdir=/etc' \
'--with-apxs2=/sw/sbin/apxs' \
'--with-config-file-path=/etc' \
'--with-config-file-scan-dir=/etc/php.d' \
'--with-freetype-dir=/sw/lib/freetype2' \
'--with-gd' \
'--with-iconv=/sw' \
'--with-jpeg-dir=/sw' \
'--with-png-dir=/sw' \
'--with-pear' \
'--with-png' \
'--with-t1lib=/sw' \
'--with-ttf=/sw' \
'--with-zlib' \
"$@"

make

Expected result:
----------------
Successful compilation.

Actual result:

This looks like a simple missing header file defining these 
constants?
