autoconf, gmake? Fine.
What about
USE_TOOLS += I_am_the_only_person_who_knows_about_this_rarely_used_tool?
I.e. how many tools (and what exactly) can be mentioned in USE_TOOLS?

> (b) mark all tools, esp. msgfmt and friends as needed
What do you think about this?
.if ${OPSYS} != "NetBSD" # I know zlib is in NetBSD base system
.include "../../devel/zlib/buildlink3.mk"
.endif

Is this good or it is always better to remove checks for a system?
What if required software is not in pkgsrc yet but I know exactly that
it is in base system (NetBSD and libbz2, for example)?

PREFER_PKGSRC/PREFER_NATIVE?
See above about libbz2.

Do you mean = only, or >= and > too?
What are "external dependencies"?
audit-packages?
