[lxml-dev] lxml Mac OS X probs?

Hi all. I saw here http://www.openplans.org/projects/bbq-sprint/nudgenudge the following text at the bottom: """Note that the Deliverance middleware requires lxml to do the theming which is known to have problems on certain platforms, e.g. Mac OS X.""" Googling for such only found problems in 2005 and 2006, and I didn't see an obvious reference to these on the lxml main page or FAQ. Can anyone give me an idea of why that comment might have been made, and what the current issues are, if any? Pointing to a web page would be fine... Thanks Gary
