[IPython-dev] trying to compile pyzmq

[Ilan Schnell]

Hello Group,

it is true that EPD installs zmq.h (anf many other header file,
other than the Python ones) in <sys.prefix>/include.  This way
the headers are always on the include path, if you use
distutils to compile C extensions.

distuils is responsible this, so it is not a hugh critical bug in EPD itself,
although one could argue that it is a bug in distutils.  However, we don't
want to change distutils default behavior in EPD.

removing the zeromq EPD package, which includes the headers is a good solution.
