confusion regarding .include vs DEPENDS

["Larson, Timothy E." <TELarson%west.com@localhost>]

Greetings,

When reading chapter 10 of the pkgsrc doco, I am confused about including
the buildlink3 file vs having DEPENDS in the makefile.  The doco seems to
indicate a preference to using buildlink3 files, but how do you specify a
minimum version for the dependency that way?  I don't want to force
dependencies to be updated when it's not necessary.

Thanks,
Tim
