There was an attempt to do something similar in 2005.
A tool called "pkg_check" was developed, and a VuXML database for OpenBSD was begun.
The tool was never added to the ports tree, and the database at
www.vuxml.org/openbsd has not been updated since January 2006.
I have not determined the reason the project was abandoned. One could always e-mail the developers and ask, I suppose, but it is moot; such a tool is neither available nor useable with this OS.
