But the libmyth library already has the lirc_client dependency, and ldd
shows it can find it.  It looks to me like the makefile for mythfrontend
has a bug that keeps it from requiring the lirc, therefore the linker
doesn't bring it in.  But I can't explain why the same fixes release works
fine in Mandriva 2006 on another machine.  Its late, maybe I'm missing
something....
