Hi. Next problem on my quest to getting Graphviz working with the  
Cairo plugin on Mac OS X 10.4.2:

I can make and install pango-1.10.0 (in $HOME/graphviz for now). But  
then when I try to make gtk+-2.8.0 it complains that it can't find a  
pango header:

$ ./configure --prefix=$HOME/graphviz --x-includes=/usr/X11R6/include  
--x-libraries=/usr/X11R6/lib
$ make

pangoxft.h exists in $HOME/graphviz/pango-1.10.0/pango but not in  
$HOME/graphviz/includes/pango-1.0/pango where I would have expected  
pango to have installed it. I can successfully make gtk+ by  
configuring like this instead:

$ CFLAGS="-I$HOME/graphviz/pango-1.10.0" ./configure --prefix=$HOME/ 
graphviz --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib
$ make

But it doesn't seem like that should be necessary. Is this a problem  
of pango-1.10.0 forgetting to install some headers, or of gtk+-2.8.0  
using some pango headers it shouldn't be using?

Thanks for your insight.
