I don't understand how this could actually be related to Nevow. Nevow is
just a Python library. If you have NameErrors, it's because you wrote
some
code using a name that wasn't defined. :) Does adding, say, "import
stackless"
to the top of your program fix the problem? If not, post some code
that shows
how it breaks.

It looks like a nevow issue in some introspection process used to import
loaders. Looking at the callstack, its actually a twisted file which throws.
Example:
#=====================
import sys
# link to standard python packages (like twisted and nevow)
sys.path.append("/usr/lib/python2.5/site-packages")
# Has no effect
import stackless
# causes Attribute Error under stackless python, fine in normal python
from nevow import loaders
#=====================
Callstack:

I thought maybe I needed to build twisted and Nevow with stackless
python instead so tried that. Twisted works, installing into
/usr/local/lib but Nevow fails at the same point as above:
[EMAIL PROTECTED]:~/Source/Nevow$ sudo spython setup.py install
Traceback (most recent call last):

forType = util._namedAnyWithBuiltinTranslation(forType)
File "/home/simon/Source/Nevow/nevow/util.py", line 183, in

return namedAny(name)

"/usr/local/lib/python2.5/site-packages/twisted/python/reflect.py", line
432, in namedAny
obj = getattr(obj, n)

I guess I am getting in a muddle ;)
Thanks for any advice and your continued patience!
