Hi Fernando, Brian,

This sounds really exciting. I am having some trouble installing pyzmq:

I used --prefix=/usr/local

[build_ext]
# Edit these to point to your installed zeromq library and header dirs.
library_dirs = /usr/local/lib
include_dirs = /usr/local/include

I checked that libzmq.so* exist in /usr/local/lib, same for zmq.* in
/usr/local/include

First I did "python setup.py build":

running build
running build_py
creating build
creating build/lib.linux-x86_64-2.6
creating build/lib.linux-x86_64-2.6/zmq
copying zmq/__init__.py -> build/lib.linux-x86_64-2.6/zmq
running build_ext
building 'zmq._zmq' extension
creating build/temp.linux-x86_64-2.6
creating build/temp.linux-x86_64-2.6/zmq
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall
-Wstrict-prototypes -fPIC -I/usr/local/include
-I/usr/include/python2.6 -c zmq/_zmq.c -o
build/temp.linux-x86_64-2.6/zmq/_zmq.o
gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions
build/temp.linux-x86_64-2.6/zmq/_zmq.o -L/usr/local/lib -lzmq -o
build/lib.linux-x86_64-2.6/zmq/_zmq.so

Next I used "python setup.py install --user" (which is equivalent to
"--prefix=~/.local"):

running install
running build
running build_py
running build_ext
running install_lib
copying build/lib.linux-x86_64-2.6/zmq/_zmq.so ->
/home/darren/.local/lib/python2.6/site-packages/zmq
running install_egg_info
Removing /home/darren/.local/lib/python2.6/site-packages/pyzmq-0.1.egg-info
Writing /home/darren/.local/lib/python2.6/site-packages/pyzmq-0.1.egg-info

Here is where I run into trouble:

Traceback (most recent call last):
  File "kernel.py", line 21, in <module>
    import zmq
  File "/home/darren/.local/lib/python2.6/site-packages/zmq/__init__.py",
line 26, in <module>
    from zmq import _zmq
ImportError: libzmq.so.0: cannot open shared object file: No such file
or directory

Any ideas? I am using kubuntu 10.04 beta.

Darren
