The best way I've found to solve this sort of problems is to use 
fpcupdeluxe, or at least the fpcupdeluxe technique. It just builds a 
fully isolated tree for each different Lazarus/fpc combinations you 
want. The trick for Lazarus is very simple, just a startup script 
pointing to the local Lazarus executable and configuration. For fpc, the 
fpc executable is just a fpc.sh which starts the local fpc with the 
local fpc config. On Linux I have two Lazarus 1.8 (one gtk2, the other 
Qt) with their fpc to support old applications, one Lazarus stable+fixes 
and one Lazarus trunk. On Mac Os the same. Give it a try.
