I've tried with both FourSuite12Processor and LibXsltProcessor now.
Still no success ..

With FourSuite12Processor, this is the line that doesn't return:
/usr/lib/python2.1.3/httplib.py(117)begin()

When I use LibXsltProcessor instead of FourSuite12Processor, I can only
trace up to libxsltmod.xsltParseStylesheetDoc .. I'm guessing that there
it dives into a C module. I get a message "xsl:include : unable to load
included.xsl" ..

=====================================================================
 > /usr/lib/python2.1/site-packages/libxslt.py(166)parseStylesheetDoc()
-> else: doc__o = doc._o
(Pdb) l
161         return stylesheet(_obj=ret)
162
163     def parseStylesheetDoc(doc):
164         """parse an XSLT stylesheet building the associated structures"""
165         if doc == None: doc__o = None
166 B->     else: doc__o = doc._o
167         ret = libxsltmod.xsltParseStylesheetDoc(doc__o)
168         if ret == None: return None
169         return stylesheet(_obj=ret)
170
171     #

(Pdb) s
warning: failed to load external entity "included.xsl"

=====================================================================

This is how I'm starting Zope:

exec /usr/bin/python2.1.3 /usr/local/zope/2-5-1/z2.py \
     -D -P 15000 -W 15800 -t 1 -u nobody

I'm using 2002-09-10-4Suite.tar.gz, PyXML 0.7.1,
Using libxml 20423, libxslt 10019 and libexslt 710
xsltproc was compiled against libxml 20423, libxslt 10019 and libexslt 710
libxslt 10019 was compiled against libxml 20423
libexslt 710 was compiled against libxml 20423

If you can think of anything else I could try, please let me know ..
