Well, it works as far as I can tell, but a potential problem is how old 
dependencies are affected (see my previous mails regarding 
libX11.so.4/libXrender.so.1)

I'll push the packages as is to /testing so someone else can do some 
more testing.

The difference between this package and the current one is just that 
/opt/csw/X11/lib(/opt/csw/X11/lib/64) is first in RUNPATH in order to 
work around the fact that there is a libXrender.so.1 in /opt/csw/lib 
which is linked to libX11.so.4 in /usr/openwin instead of "our" own in 
/opt/csw/X11.

But this still isn't a complete solution in order to link with libcairo 
without linking with libX11 from openwin. This version of libcairo only 
takes care of the runtime problem, when building apps/lib using libcairo 
you still need to prepend -L/opt/csw/X11/lib (-R/opt/csw/X11/lib if your 
app/lib uses X11 stuff in other places and not just as a result of 
linking with libcairo) to your link command.
One way to do it when using GAR is to set:
EXTRA_SOS_LD_FLAGS = -L$(abspath $(prefix)/X11/lib/$(MM_LIBDIR))
(and if needed:
EXTRA_SOS_LD_OPTIONS = -R$(abspath $(prefix)/X11/lib/$(MM_LIBDIR))
)
