Hmm, I just remembered something:

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--
< Domo_> For me the 'shr test fails by missing libxml-parse-html-region ...
< Domo_> which is defined in src/xml.c -- and exists by default on 
         another emacs...
< Domo_> which probably means that my self-compiled emacs24 just doesn't 
         have that xml code compiled in :(

< Domo_> ...
< Domo_> #endif /* HAVE_LIBXML2 */
--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

So, this is something to be checked for -- installing 
libxml2-devel-2.7.6-8.el6_3.3.x86_64 (on Scientific Linux 6 machine)
and rebuilding emacs made things work for me.

I'd guess the recipe to build emacs 24 on gentoo had this dependency
but maybe emacs24 is so new that at the time buildbot machine got
emacs24 that wasn't there yet ???
