	I believe there were changes in the API for the library between
	versions. gtk i still quite a young project and they were more
	interested in "getting it right" than retaining backwards

	Recently updated pkgsrc to move the files for
	gtk-1.0.X and change the programs that referenced it so that both
	old and new programs can coexist.

	If you update your pkgsrc, and  then delete the old gtk1.0 and any
	programs needing it you should be able to remake and install both
	old and new at the same time.

	I don't know about the Mesa demos - I'll try the latest version
	from pkgsrc out on an i386 box here and se if I can replicate your
