Can you try git HEAD pango as well please.. there is a tantalising
sounding commit which has not made any release yet:

    [cairo] Scale font metrics to user space
    
    Bug 457990 - font metrics are not converted to user space in cairo backend


Of course.. it is working on Linux (and OS X when build in a particular
way), so this would only be useful if this bug happens to be affecting
the OS-X native back-end (assuming that is what you're building for).

Are you building with Quartz / ATSUI or freetype font rendering (as you
would get on Linux)? (Pango and Cairo need to match in this regard).

Are you building to run on the X11 server in OS X?

Try building pango with --with-x 

(I think cairo needs to be build compatibly first)

--enable-xlib=yes --enable-xlib-xrender=yes --enable-quartz=no
--enable-quartz-font=no --enable-quartz-image=no --enable-ft=yes
--enable-fc=yes

(This ought to get you building a X11 "like" cairo).

I'd be really curious if you can get something working, if you could
also nail down what causes it to break again.


Btw.. I don't think you need to rebuild GTK each time, but I might be
wrong. Give it a try without first if you can.

Best wishes,

Peter C.
