Building KDevelop3 RPM on Fedora 14

[Sonic]

Hello

    I'm trying to build KDevelop 3.x RPM for Fedora. I wish to call it 
kdevelop3 and be able to have it along with kdevelop (KDevelop4) that 
comes bundled with Fedora. Does this 'wish' have serious flaws to 
require considerable effort to implement?

I've made the following changes to the SPEC file:
1. changed 'Name' in the SPEC file to "kdevelop3"
2. added --program-suffix=3 to configure

Are the above changes sufficient or should I also add --prefix=SOME_PATH 
to configure script?

Also, how do I meddle with the .desktop entries in the launcher menus to 
call this KDevelop3 (like "Qt assistant" and "Qt4 Assistant")?

Any help is highly appreciated..
