There are no 64 bits rpms for lazarus, except for snapshots.

So either use the snapshot rpms (http://www.hu.freepascal.org/lazarus/), release 
source rpms 
or follow the steps to compile from source:

Note, that you need three things: fpc, source code of fpc units (for code 
completion, e.g. fpc-src-2.0.2.xxx.rpm) and lazarus
