Well, that's annoying. I had to upgrade it because the latest SnowLeopard upgrade didn't like libxml2-2.6. I guess I'll have to add a branches["libxml2"] entry in jhbuildrc-custom to use the older version. (Good thing I took out the checksum, I guess. At least that won't choke, though something else will, I'm sure.)

I'm not where I can use my 10.4 build machine. Could you add 
branches["libxml2"]="libxml2/2.6/libxml2-2.6.30.tar.bz2" 
to your jhbuildrc-custom and see if that works? If it does (and you report back before I get home in a couple of weeks), I'll commit a change to jhbuildrc so that it's automatic on Tiger.

Have you tried building gtk-2.90 on Tiger?
