That would require using FPC/Lazarus with root privileges...not recommended

I solved the fpc.cfg issue anyway by having the 2.4.0 config file in 
/etc, and 2.5.1's config file in ~/.fpc.cfg

However, another idea just came to my mind: Can #IFDEF within fpc.cfg be 
used to test the value of $FPCVERSION? This would allow conditional paths.
