pcc has been added to NetBSD (via pkgsrc) and OpenBSD, and Steve Mynott has been messing with it on DragonFly. It doesn’t work as a replacement for GCC, but it looks promising. There are other alternatives in progress, too.
A running description of activity related to DragonFly BSD.
There is also nwcc, though not hugely impressive, it’s out there too. On sourceforge.
PCC was added _only_ to pkgsrc, not to NetBSD(‘s base).

Duh, it says NetBSD (pkgsrc), are you blind Hubey?
I edited it to say “via pkgsrc”, just to be more clear.
