Can the port command take advantage of multiple cores?

So every maintainer has to check for himself if his/her ports built fine 
with parallel building enabled? With this approach it will last a long 
time until we get real benefits of parallel building. Although many 
users already own multi-core Macs and want to have faster builds...

I don't think that many ports will break with this. As Yves said, 5 out 
of 150 failed for him. Tagging 5 ports is easier than tagging 150.
And it would be not a real problem if a port fails, there is always the 
workaround to disable this option in macports.conf again until the 
Portfile for a failing port is modified accordingly.
