No, there aren't. We would like to have this, but the infrastructure  
and code for this do not exist yet. There are also license issues to  
consider.

Yes, it does.

build_make_jobs in macports.conf. "0" means as many cores as are  
available, though the number is reduced if you have less RAM.  
Individual ports might disable parallel building if they are known to  
be incompatible with it.

All gcc ports have been broken in Snow Leopard until very recently,  
but I was able to install gcc43, gcc44 and gcc45 yesterday. Please  
"sudo port selfupdate" to make sure you have the very latest ports,  
then try again.
