The other problem with parallel builds is that they are not identical

ports several times with parallel build on to see if they repeatably
build correctly.
If the port does not build correctly the dependencies in the Makefile
are wrong. If it ever fails for someone and he/she files some ticket it
can be disabled. Usually there is no need to test it multiple times or
something like that.
I think "multiple times" may be a proxy for "under slightly different
circumstances that trigger race conditions"...
As I said before in other emails, we will not be able to provide
packages for each and every variant combination (that would be 2^n for a
port with n variants). So building custom ports on the end-user side
will still happen even once we ship binary packages for default_variants.
Good point. If you can hit 80% of the user base with binary builds,
you've made a lot of people very happy.
(That said, I am very pleased with the build speed on my shiny new
dual-quad-core-Xeon 3.2GHz Mac Pro with 16GB RAM, four Cheetah 15K.5 SAS
drives, and ccache enabled. I just want to throw that out there. You
know, as a data point.)
