Yep, that does seem to be the case - cabal shows "Versions installed: 8.5.4, 9.1.6". The module referenced in the website example - Text.XML.HXT.DOM.XmlTreeFilter and function isXText - has only old packages, so when installing hxt I got version 9.1.6, but from hxt-filter I got hxt 8.5.4, so that's why the example fails.
