The quirks package shown here belongs to current.
I guess you are not running OpenBSD 6.5 release but a snapshot at some point and that you havent updated your version before trying to add vlc. It is important to use an OpenBSD version and packages matching each other in time.
Don't be misled by the output of the uname command. Use this one instead :
Code:
$ sysctl kern.version
If I am right you have 2 solutions:
- upgrade your OpenBSD version, update your packages and then add VLC:

Or
- reinstall your system with the 6.5 release and install VLC (here all your data are gonna be deleted).
