I'm trying your 'cheesy hack' now Tom on the LiveCD.  It didn't seem  
to work initially as the Makefile in the 'bin' subdirectory wasn't  
receiving the 'gcc -shared' instruction/directive.  Just to be sure  
its not a weirdness on the liveCD's part, I'm going to start again.

I'll keep you posted.
