I can not install the development software at debian, download after the implementation will make mistakes, what is this problem?
What are you trying to do?
Your problem description is does not reveal anything.
Are you trying to build a lmce devel system on top of debian?, why not use kubuntu 8.10 as base which is what we use.
Debian may work but that is not the system be build upon.
Only my 2 cents.
