Unless you need the Imon program (which is only useful at a GE 3 Tesla scanner), I recommend you just compile with "make -i totality". The "-i" flag will tell make to ignore errors and proceed. You'll end up without the Imon program, but if you don't need it, you won't miss it.
The problem is that the Makefile for Imon (in directory rickr/) is special for the GE realtime workstation.
