EDE was ported to OpenBSD and packages are available for various architectures. You can either install EDE from these packages, build it from the ports or compile and install it manually.
Being part of the OpenBSD distribution, you do not need any external package source for EDE. It can be found on any official mirror.
Packages are available since version 5.4.
OpenBSD has packages for the i386, amd64, hppa, mips64, powerpc and sparc64 architectures as of version 5.4.

Building your own packages from ports is actually as simple as changing to the directory of the EDE port and issue the make command. This will build and install any dependencies missing on your system, too.
You may want to take a look at the dependencies first and think about various flavors!
E.g. the doxygen package draws in the heavy Qt toolkit by default which may not be desirable on a light-weight system. For that reason there's the “no-gui” flavor of it.
cd /usr/ports/x11/ede make install
Alternatively you can of course follow the generic building procedure, too: InstallingFromSource.
You can either use a graphical login manager or start it using startx. In the later case edit the .xinitrc file in your user's home directory so that it just launches EDE. The line for that is the following:
exec startede
EDE as packaged by OpenBSD seems not to use the modified PekWM that comes with EDE but the mainline one. Thus the default configuration is not like that of EDE on other systems.
