Installing RRDTools on OSX

Phew.. Finally got the darn thing to install...
I better put this in here for posterity.

sudo cp /usr/X11R6/include/ft2build.h /usr/X11R6/include/freetype2/
PKG_CONFIG_PATH="/opt/gtk/lib/pkgconfig"
CPPFLAGS="-I/usr/X11R6/include/libpng -I/usr/X11R6/include/freetype2 -I/usr/local/lib -I/opt/gtk/include/libart-2.0 -I/opt/gtk/include -I/usr/local -I/usr/X11R6"

LDFLAGS="-L/usr/X11R6/lib -L/usr/local/lib"
CFLAGS=-O2
export CPPFLAGS LDFLAGS CFLAGS PKG_CONFIG_PATH
