ruby 1.8.7 can parse these data.

FWIW, I checked and raquo is a valid entity in XHTML 1.1, the page passes validation, and it correctly states the XHTML 1.1 DTD.

The entity DTD also seems to be included in the modular framework module, a required part of XHTML as per http://www.w3.org/TR/xhtml-modularization/schema_module_defs.html#a_character_entities

i.e. the XHTML DTD includes xhtml-framework-1.mod, which includes xhtml-charent-1.mod, which includes xhtml-lat1.ent, which defines the raquo entity.

It seems that this bug was fixed. I can parse the page with ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux] under ubuntu 10.10.
