Hi,  Beni and Jake.

With the current version of the build system it looks like one needs to 
do an explicit "make install" in the programs/Simulation/hdds directory 
in order for the hddsGeant3.F file to be copied into the 
programs/Simulation/HDGeant directory before you compile hdgeant.    
Perhaps you were running with the old broken FDC geometry without 
knowing it?
