Pardon my ignorance, but is there a PKG_DEPENDS, to list packages that the
current item depends on?
If so, may I suggest a possible extension to the naming convention for
packages as used by this entry :
package-major.minor to require an exact version of a package
package to require any version of a package
package>major.minor to require version major.minor or higher.
And as well, a PACKAGE_USES entry to indicate other packages that aren't
required, but _are_ used (for extra features, etc).
