[kw-pm] auto-deps for perl 'usr lib' directives in makefiles?

[Robert P. J. Day]

  is there a way (as with C include files) to have perl programs have
auto-dependencies that are processed by makefiles?

  example:

	use lib (..., ..., ...) ;
	use module1 ;
	use module2 ;
	use module3 ;
	...

obviously, this program might be dependent on changes in those libs,
and, while one can hardcode those .pm files into the makefile before
this program is run, is there a better way to do it?

  (i'm *really* tired this morning so i'm almost certainly barely
coherent.)
