Ah - If .gif support (e.g. "nonfree") was the issue, then yeah.  What
Henry said. :)

Also, you can use NetPBM like so:

  pngtopnm SOME.PNG | pnmquant -fs 256 | ppmtogif > SOME.GIF


Where "pnmquant -fs 256" makes a Floyd-Steinberg dithered image of 256 colors.
You can also use palettes and other good stuff here, too.  (I believe the
format of the "palette" file you can use with 'pnmquant' is simply
some .PPM file.)


Good luck!
