Unable to use Diazo (plone.app.theming) on Centos

Question

I made a webportal on my mac using plone4.1 and Diazo.

Now, I'm trying to deploy it on my server (CentOs) where there is yet another site with plone4.0.5 + collectivexdv.

When I run the site (in a brand new buildout) with my diazotheme I obtain this lines via shell (instance fg):

2011-09-27 09:32:10 ERROR plone.transformchain Unexpected error whilst trying to apply transform chain

  File "xslt.pxi", line 568, in lxml.etree.XSLT.__call__ (src/lxml/lxml.etree.c:120289)
XSLTApplyError: xsltValueOf: text copy failed

What's the matter?

I had the exact same problem and it's due an old libxml2/libxslt. Add these lines on your buildout:

[buildout]
parts =
     lxml # keep lxml as the first one!
     ...
     instance

[lxml]
recipe = z3c.recipe.staticlxml
egg = lxml
libxml2-url = ftp://xmlsoft.org/libxml2/libxml2-2.7.8.tar.gz
libxslt-url = ftp://xmlsoft.org/libxml2/libxslt-1.1.26.tar.gz
static-build = true
force = false
