Now 38 are installed and it has never shown more than 1 running.
Appears to be doing them all one by one.

I'm not sure what you mean about system being setup for parallel jobs.

Isn't the new default emerge to run that way?  Isn't that why we now
have this line about jobs and load that completely removes the old -v
ouput?

This is a brand new install, and I've changed very little.  I've done
nothing consciously to effect how many jobs are to be run.

If its only going to do the jobs one by one, then why cover the -v
output?

I'd sooner disable this new behavior but it appears there is no across
the board way to do that.  Maybe a function like:

  emg () { emerge --quite-build=n $@; }

Would have that effect.  I can't see where it would be losing anything
since emerge is doing 1 job at a time anyway.  By the way, are these
heavy or unusual loads:

   1.10 1.17 1.14

Its an i7 processor but gentoo is running as vbox guest.
