set is a built-in set data type in Python 2.4 and later. Twisted

to import set) has

set = set
except NameError:
from sets import Set as set
which simply tests to see if set is defined, otherwise it imports
it From the sets module, which defines a Set class in old Python
versions.
Have now added this line, and I get the error
Uh, it was supposed to be a solution for you to add :-( It was an
explanation that you have a broken installation of Twisted.
First of all, Python works no unlike Java with regard to it's PYTHONPATH
environment variable. On my system I have installed Twisted into
~/opt/lib/python/ and have set PYTHONPATH to that same value.
Inside of ~/opt/lib/python/ I have

You can check that things are installed nicely by switching to some
other directory and starting the interactive python interpreter:

Likewise for GMPY:

x = gmpy.mpz(1234567891234567891234567)
len(str(x**12345))

Which Python version are you using (python -V)? Which distribution is
this? Twisted is a standard component which is surely packaged for
the distribution -- there should be no need to installing it
yourself.
Python 2.4.3 (#1, Sep 3 2009, 15:37:37)
That is fine, we have an old Redhat here with the same Python version.
We have Centos as the OS, it is a managed distributed system.
- i.e. the filestore is shared and used by 150 odd machines.
So I cant just add packages etc. If I want something installed which my
path does not pick up I either have to
a) Search around to find it on the system
or
b) Install it myself in my own space
Clearly b usually takes less time ;-)
Heh, yeah.
Also no-one in the dept seems to use python for anything, so I doubt
python related stuff is instaleld. Which means option a is unlikely to
work.
It's not like it will mess things up to install Python, Twisted, and
GMPY globally. The packages will just sit nicely in the corner and
nobody will notice :-)

I have actually installed a whole new version of twisted, Zope, gmpy
from scratch this week.

Okay, so some things are working... I'm afraid I don't know why you get
the import errors you reported in the other mails.
If you can give me SSH access to the machine, then I can take a closer
look. I've yet to meet a machine where I couldn't get VIFF running :-)
I've put my SSH public key here:

No, it's not as bad as it sounds -- they switched from version 2.x to
version x.something where x is used in year 200x :-)
