Lazarus has the --pcp= commandline option which defines the primary 
configuration path, hence the location of the FPC compiler binary and 
library sources. I've copied the source tree into an appropriate place 
in /usr/local/lib/fpc (i.e. fpcsrc is next to ppc386) and can generally 
run the current and preceding versions without problem.

As was pointed out to me a couple of weeks ago Lazarus doesn't have a 
configuration macro showing the FPC version it was built with, it goes 
and determines the FPC version using the path it's been told to follow.
