Yes, I saw that configure invokes cc.
I suspect that it might be a fake compile just to check that all files 
can be found and are in place, no more than just that.

Anyway, freetype is found now.
I overlooked one thing: to copy the freetype include directory to 
OctaveLibs/include

So, building right now - tomorrow morning I'll see how far the build goes.

Thanks
