-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Yeah I figured that I would be able to pass the -j flag to make but was curious of whether it was possible to do globally. I realize that some ports might not be particularily happy about it. Let's introduce another ports flag for safe multithread compiling, MULTISAFE= YES ;) If the flag is set to no it will default to just one job, otherwise utilize whatever the value is of -j. Anyways, thanks for your reply.
