That is quite a strange error, but cBanana is not required nor even 
enabled by default these days.  This is harmless.

What's much more important to see is *how* twisted.web fails.  The 
cBanana stuff is totally harmless, though it sounds like Xcode might 
not be installed correctly if you're getting strange compile errors 
like that?

Did you remember to python setup.py install?  build won't install 
anything.

FWIW, Twisted should run without ANY C extensions or ANY compilation.  
You can just point sys.path to /code/Twisted-1.3.0 and it will have a 
working twisted package.

Also, the cfreactor in 1.3.0 is broken for PyObjC 1.1 and later, so 
maybe you should be trying Twisted 2.0-SVN instead..
