No I didn't know what, thanks.

Just tried that... :(

I updated my system, if there is a bug in Xpm it hasn't been fixed (some 
how I doubt it's a bug - it's more likely me doing something daft).

Interestingly if I take the program off it still complains...

ocamlc `camlimages-config` -cclib "-L/usr/X11R6/lib -lxvthumb -lXpm 
-lX11 -lpng -lfreetype -lz -ljpeg -lgif"

So I guess that it comes from linking with the ocaml files specified in 
camlimages-config with the libraries...

-I /usr/lib/ocaml/3.07/camlimages ci_core.cma ci_gif.cma ci_jpeg.cma 
ci_tiff.cma ci_bmp.cma ci_ppm.cma ci_png.cma ci_ps.cma ci_xpm.cma


If i leave ci_xpm.cma off, it links.  I don't know if it's safe to leave 
it off.  I suppose if I don't use XPM it'll be ok, but it's not the 
greatest solution.
