[GEM-dev] ARToolkit issue on 10.4/Intel

[Hans-Christoph Steiner]

So I installed artoolkit from Fink, and Gem gives this build error,  
which is new to me.  Is it worth trying to get artoolkit support into  
the 0.92 build in the current Pd-extended builds?

An Apple person recommends adding -fno-common to the build:
http://gcc.gnu.org/ml/gcc/2005-06/msg00378.html

Others recommend not using multi_module mode, and sending - 
single_module:
