When building Linux examples, they fail. #9

It seems that after installing SDL and trying to build, some examples fails to build with missing functions error (see below). Should the rest of the examples still work if started manually via SSH?

I don't currently have a clean copy of what's on github installed on a pi but give me a little time to recreate the environment and I'll check this out. From a quick glance, I have a vague recollection that '-lm' has to be the last item on the command line.
