Heh, that's what we're doing in pkgsrc... we define _PKGTOOLS_VER by
looking at the binaries, and then require a certain version (or above). 
If anything below that requested version is installed, we instruct the
user to upgrade. This could be handled automatically. 
See line 546+ of pkgsrc/mk/bsd.pkg.mk.

Works great! :)
