There probably is a /dev, but it's hidden by the Finder. In a terminal
you should be able to run "ls /dev". This problem is caused by non-root
users not having permission to the bpf device. A workaround is to run
with sudo. A permanent solution is to install the ChmodBPF script that
comes with Wireshark.

You are brave to try compiling all of Zenmap's dependencies from
source--that's not the recommended procedure because there are so many.
Do you know about the installer for Mac OS X?

http://nmap.org/download.html#macosx

If you're going to install Zenmap from source, don't compile all the
dependencies manually. Use a packaging system like MacPorts. That will
solve all your problems with finding new enough versions of libraries.
With MacPorts, you have to install the packages py25-gtk, py25-sqlite3,
and py25-zlib, and then configure Nmap setting the PYTHON environment
variable to the path of the Python interpreter installed by MacPorts.
