Please check first whether there are any old `.gpi' files present that have been compiled with gpc-2.0. The GPI format has changed significantly between both versions of GPC, so all `.gpi's need to be rebuilt.

OK, now I get gpc: Internal compiler error: program gpc1 got fatal signal 6 *** Error code 1 make: Fatal error: Command failed for target `soil_h2o.o' Being a novice, this is highly likely to be something pretty dumb.
