Q; kdevelop installation

[D. R. Evans]

I need to install kdevelop.

In adept, it seems like there is a kdevelop and a kdevelop3, and it's
not obvious what the difference is, except that kdevelop is at version
3.3.5 and kdevelop3 is at version 3.3.2.

So, since the kdevelop package seems to be more recent, I installed
that. I also installed kdevelop-dev and kdevelop-doc. The kdevelop
package installed kdevelop-data.

But even after installation of these packages:
1. There is no KDevelop item on the menu
2. If I type "kdevelop" in a console, kdevelop tries to start but
complains that it can't find any plug-ins.

Does anyone know what other packages I need to include in order to get
a functioning kdevelop?
