I fixed the orb.h just recleaning and starting again from scratch.
I'm not getting this error though:
../../../gem-0.86/src/AuxLibs/particle -I../../../include
-I../../../GemLibs/glm -I/usr/local/include -I..
/usr/bin/ld: cannot find -lparticle
collect2: ld returned 1 exit status
make: *** [Gem.pd_linux] Error 1
not sure about this one, I don't know enough about compiling to fix the -lparticle lib problem... run ldconfig?
