Thanks for the additional input, Hika and Karl. I had seen that and did 
look a bit into the --noreplace switch as a possible resolution but had 
decided using that would probably not be advisable. The reason being that, 
as I had understood, using that switch would cause a particular version of 
php to be added to the world set. This being a dedicated MythTV box, it is 
necessary to have php in the world set. But theoretically, the machine 
could last long enough for php 5.6.30 to become deprecated; given that 
possibility, would it not be inadvisable to have a particular version of 
php stipulated in the world set? It might sound a bit unreasonable, but I 
would hope this machine might even still be in service til php 7 is 
deprecated in favor of whatever new version might succeed it. So, again, 
as I'm understanding it, having php in the world set, without stipulation 
of a particular version, would seem to me what is called for. But I am 
obviously no sort of gentoo aficionado and am likely misunderstanding some 
fundamentals of administering a machine running this distro which, after 
all, is fairly new to me and is really still barely within my competence.

Apologies to the list for these somewhat off-topic posts.
