[Lazarus] Custom composite components issue with latest Lazarus

[Michael Schnell]

Graeme,

While with the most recent Lazarus svn and fpGUI git sources I can 
compile and my Event Test demo program for the Build Modes "gtk" and 
"gtk 2", when switching the LCLWidgetType Macro to "fpGUI" I get:

"fpgui/corelib/fpg_base.pas(27,3) Fatal: Can't find unit fpg_impl used 
by fpg_base"

Whats up ?

Thanks,
-Michael
