No we don't have a 10.5 i386 builder, and as I said there's practically no reason why anyone should use such a system, since all Intel Macs that support 10.5 can and should upgrade to 10.6.

We do, on the other hand, have a 10.5 ppc builder, because that is the last version of Mac OS X that works on PowerPC computers.

I fixed it on 10.5 Intel. It works fine now.

I believe I previously stated that if a port installs another compiler via MacPorts, then it is because we found that that port is not compatible with whatever compiler would otherwise have been chosen. So there must be some port that you've installed that is not compatible with Apple gcc 4.2.1 build 5577 (which came with your Xcode), and instead requires the slightly newer Apple gcc 4.2.1 build 5666 dot 3 (which is in MacPorts).

So the simple answer to your question "why" is "because it is needed".
