You could try activating the non +universal version to get a dependency
error. Then do the same for the dependency, and so on back to the first
port built +universal.

So, yes it seems that the on the new machine I ended up with gcc6

dependents, and I didn’t explicitly install it. So, I’m not sure
what caused it to be installed. And, on the new machine it, and
the chain down, installed +universal, while on the older machine
it installed the default variant. Both computers installed gcc6
6.2.0_2.
So, my academic question is why did this happen? And, the related
questions are what port would have installed gcc6? Since I see this:
$port dependents gcc6
gcc6 has no dependents.
I don't know. If you don't need gcc6, don't install it / uninstall it.
It appears that build dependencies don’t show up with the
dependencies command? So, some installed port might have required
gcc6 to install, but doesn’t need it for runtime.
Try with this:
port echo depends_build:gcc6 and installed
This is only using the information from the latest ports tree, but could
probably answer your question.

Thanks that helps. It is a step in the right direction, but still
leaves my question about what generates all the extra universal builds
on the new machine, when the old machine had mostly default.
For example, on the new machine the above shows that py27-numpy has
two installs, with the active one being +universal. So, the migrate
script first installed it default, then due to yet another port, must
have rebuilt it +universal. But, I don’t know how to trace those back
to the root of it.
Perhaps the least effort would be to remove +universal completely from
myports.txt then uninstall everything, and then reinstall with the
migrate script? Would anything that needs to be universal then end up
getting put back that way?
