How to disable an update for a specific program.

[kubuntu]

Hi all,
I have recently installed lazarus-1.0.4-0.x86_64 fpc-2.6.0-2.fc17.x86_64 
and fpc-src-2.6.0-2.fc17.x86_64. I downloaded these x86_64 versions in 
rpm format and converted to deb using alien then installed using 
apt-get. This all worked well and I am able to use lazarus without any 
problems.
However, software updates wanted to update fpc to 2.6.0-6, which I did.
I was then left with a non working lazarus because it could not find the 
fpc executables, I search my computer and could not find them.
My original installation had them in /usr/lib64 but the update did not 
put them there, in fact I'm not sure that the update is even for a 
x86_64 system.
So I removed the fpc software and reinstalled my deb package and all is 
working again.
I am still getting requests to update fpc.
How can I disable the system from requesting update of just this software?
Hope all is clear
Paul
