I just tried to investigate on of my currently broken packages, and see
a file dependency on config.h in ExtUtils::MakeMaker generated
Makefiles.

i.e. no compilation is involved, and no dependency on gcc or any
library, this Makefile simply depends on the _file_ config.h.

I haven't yet checked what it is used for.

Well, yes, you made an implicit dep visible. 

The question is "which dependency" and is kind of package split useful
(There is no doubt that a split between a "c-devel environment" and a
run-time environment is useful.)
