I upgraded my X client box to 1.6 yesterday, to start playing with GTK2.
My X server is still NetBSD 1.5, XFree86 3.3.6. According to xdpyinfo,
SVGA doesn't support the RENDER extension.
The X client box is where I built and want run Bluefish, a GTK2 app. The
box has X installed (but not configured) only because it was easy to say
Bluefish builds but does not run:
> $ bluefish --help
> Xlib: extension "RENDER" missing on display "lowden:0.0".
> No fonts found; this probably means that the fontconfig
> library is not correctly configured. You may need to
> edit the fonts.conf configuration file. More information
> about fontconfig can be found in the fontconfig(3) manual
> page and on http://fontconfig.org
I wrote to bluefish-dev about this, and received:

Ush. I think I'm in, as George's dad used to say, deep doo-doo.
I'm posting this message for two reasons:
1. If true, the RENDER extension requirement represents a subtle
dependency, one that perhaps needs some environmental control. The right
answer can't be reached by interrogation, because the builder can't know
the display's capabilities if it's remote.
2. To seek advice. What to do? Try to exclude RENDER requirements from
the pkgsrc version of GTK2? Upgrade the X server on my workstation?
(meaning I have to upgrade it, too, which I was trying to avoid for now).
Would xonx be any help?
