mesa libs issue

[Tatsuki Makino]

Hello.
Does anyone reading this know how to upgrade more easily from below?

#1. Collect mesa packages.
pkg version -L = | grep "?" | grep "17\.0\.3" | cut -w -f 1 > /tmp/mesa_pkg.txt

#2. Collect the required origin that exists.
sh -c 'xargs pkg query %ro < /tmp/mesa_pkg.txt | sort -u | while read o ; do [ -d "/usr/ports/$o" ] && echo "$o" ; done' > /tmp/mesa_req.txt

#3. Forcibly delete mesa packages.
xargs pkg delete -f < /tmp/mesa_pkg.txt

#4. Reinstall the required package.
xargs portmaster < /tmp/mesa_req.txt
