>Description:
Although security/openvas-* is currently not buildable because of

BROKEN="Does not build with gnutls-3.5 -- newer versions available."

in security/openvas-libraries, this seems easily fixed. And indeed, with the current gnutls-3.7, the openvas package happily compiles - but still doesn't run.

Before diving into fixing this issue, the committed user hopefully realizes, that the source archives downloaded for openvas date from 2009!!! Any attempt to get this software running would be a waste of time at best and outright dangerous at worst.

I think openvas-* is not even worth keeping for academic reasons, it is able to do more harm than good in pkgsrc. Unfortunately, the current version of this software (Greenbone, https://greenbone.github.io/docs/) does not build out of the box on NetBSD, but its inclusion in pkgsrc would be a real benefit.
>How-To-Repeat:

>Fix:
rm -rf security/openvas-*
