Greetings,
So pkg wants to upgrade perl to 5.18.  It appears that due to
conflicts with existing 5.16 binaries, this requires deinstalling
224 ports, including xorg, and all that implies.  I see a lot
of things like python libs(!) nuked as collateral damage

Am I missing something?  Is the following procedure my only
option?

1. pkg remove perl5 (and basically the installed system,
   including xorg)

2. pkg install perl5

3. pkg install ${224 ports}

Thanks,
Russell
