libgd conflicts with uk-libgd

[Pierre Abbat]

On installing gnuplot, I got a problem. pkg check -d reported this:

pkg updating has a notice from four years ago about libGL which says to use 
portmaster. Is it still valid? Should I use portmaster?

When installing all the packages for gnuplot, it installed uk-libgd, but that 
conflicts with libgd. Which one should I have installed?
