I believe you can ignore the message, as long as you upgrade any remaining outdated ports later.

texlive depends on texlive-bin-extras, and texlive-bin-extras used to install a copy of the dvisvgm program. But we also have a standalone dvisvgm port which provides the same problem which was confusing. To solve that, so texlive-bin-extras was recently changed to no longer install its own copy of dvisvgm and to instead rely on the one in the dvisvgm port. When upgrading, it is necessary for the dvisvgm port to force the texlive-bin-extras port to deactivate, otherwise an activation conflict would occur. Deactivating texlive-bin-extras breaks texlive, hence the message you saw, but as long as you upgrade texlive-bin-extras afterward it will reactivate and there is no problem.
