They are called from the fetch, extract and install targets,
respectively.
Also, only RUN_DEPENDS is put into the @pkgdep list of the package.
EXEC_DEPENDS is still supported (for now), it is copied into
BUILD_DEPENDS and RUN_DEPENDS. This will go away after we finish
fixing all the ports Makefiles.
This change fixes the following bug/features:
(1) "make fetch" building and installing all the dependencies
(2) Programs needed for building only (e.g., gmake) put into the
packages' dependency lists ("why does the emacs package depend on
gmake?")
