I shouldn't be too hard to create a port, just be careful to consider
the architecture dependency of the binary package you are using.
If multiple architectures and OS releases are supported, then you'll
have to create the package name from those parameters and provide
distinfo data for all supported combinations of architecture and
OS release. You can override the name of the DISTINFO_FILE in the
port's Makefile to have separate distinfo files per arch/version.
In the port's Makefile extract the contents of the correct package
into the stage directory, have dummy targets for phases that are not
reuquired (e.g. an empty do-stage to have the stage done marker set
in the ${WRKSRC} directory) and provide a pkg-plist (possibly multiple
variants selected by the PLIST variable, if there are arch/version
specific differences).
Use ONLY_FOR_ARCH and IGNORE to limit the package building to those
architectures and releases that are supported, to prevent package
fall-out messages and to give ports users a reasonable error message
when trying to build the port on an unsupported system.
The generated package will have the meta-data from your port. If
you want to preserve some meta-date from the pre-built package, then
extract it from the extracted distfile, e.g. in the build phase.
Else use NO_BUILD to suppress this and possibly other phases that
are not required (empty dummy targets will do as well).
