vlc - gtk2/3 symbols problem

[AN]

Hi:

On a new install of 12-current vlc is failing to start:

FreeBSD FBSD_12 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r314495: Wed Mar  1 
18:14:24 UTC 2017 
root at releng3.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64

Starting vlc on the command line fails with:
# vlc
VLC media player 2.2.4 Weatherwax (revision 2.2.3-37-g888b7e89)
[00000008024233f0] logger interface: using logger.

and GTK+ 3 in the same process is not supported
