Thank you for this information. It did help me to go further.  
Changing 'module.append_autogenargs' to just 'append_autogenargs' is  
what worked for me.

I couldn't find the autogen.py file, so I just let jhbuild crash.  
Using the --start-at option made things continue.

I did notice that Cairo 1.14 needs a patch to build on Mac OS 10.4.  
Here are two patches that allowed me to successfully build Cairo.


The code for extracting font glyphs was replaced in
70cc8f250b5669e757b4f044571ba0f71e3dea9e with an implementation based
on CoreText, which is not available on MacOSX 10.4.  This commit
restores automatic detection of which API should be used by means of
dynamic linking.

When I was at module 18 (gtk), it failed due to this error:

In file included from GdkQuartzView.c:21:
GdkQuartzView.h:37: error: cannot find protocol declaration for  
'NSTextInputClient'
In file included from gdkwindow-quartz.h:25,
                 from GdkQuartzWindow.c:22:
../../gdk/quartz/GdkQuartzView.h:37: error: cannot find protocol  
declaration for 'NSTextInputClient'
make[4]: *** [GdkQuartzWindow.lo] Error 1
make[4]: *** Waiting for unfinished jobs....
make[4]: *** [GdkQuartzView.lo] Error 1

The NSTextInputClient protocol is defined in Mac OS 10.5+, so it  
wasn't available on my system. The solution to this problem could be  
to develop a patch that conditionally uses this protocol. Or maybe I  
could use and older version of GTK that did compile successfully on  
Mac OS 10.4. Anyone know what version that would be? I'm guessing  
around v3.0.
