You have done it right this time and portage is doing exactly what you
tell it to do. unfortunately that is not the same as what you want it to
do.

MAKEOPTS governs the number of parallel processes executed by a single
compile. So your setting it is allowing parallel merges, but each one uses
only one CPU core.

I don't think what you want can be controlled by package.env, since you
want to change an emerge command line option, not an environment
variable. What you want requires "emerge -j 1".
