Rob,

The normal simh makefile knows how to find the necessary SDL pieces on all *nix platforms (including MacOS X).  Building a simulator that could use the functionality provided by libSDL produces messages at build time advising if all of the potentially useful features aren't available and how to get the useful pieces on the platform the build is running on.  All your simulator needs to do is follow the pattern used by other simulators.  If, libSDL isn't being used directly by the simulator proper and only your frontpanel application, then the makefile structure would be is similar just for the frontpanel build target.  Show me what you're trying and I'll make some suggestions.
