No, currently, it only compares patch level numbers (not version

numbers) and even that only within the same package repository.
Perhaps setting your PKG_PATH might get part of your job done.

The program pkg_add only considers the packages form the first

repository in the PKG_PATH where it finds at least one matching one.

With the current scheme, considering installed packages as an

additional pseudo-repository is not possible and would not make

any sense: If that pseudo-repository were put at the beginning,

no package would ever get updated, were it put at the end,

it would have no effect whatsoever.
Consider
export PKG_PATH=/usr/ports/packages/386/all/:ftp://openbsd.ftp.fu-berlin.de/snapshots/packages/i386/
or whatever architecture, flavor and mirror you are using.
But if use such settings, do not forget regularly cleaning obsolete

packages out of the directory /usr/ports/packages/386/all/.

With the PKG_PATH shown above, they will always override the public

mirror, even when they become outdated and the mirror has newer ones.
Hope that helps,

  Ingo
