Here's a message from the -users list just now: On Jul 28, 2007, at 18:39, Chris Waterson wrote:
Hey, I had the same problem. It turns out I was using an older version of Xtools (specifically, version 2.3). After upgrading to Xtools 2.4.1, things worked fine. (The specific trouble, which you can see if you get rid of the "-j2" option in the makefile, is that they've changed some of the defines in the header files that the boehm-gc needs.)
Problems caused by old Xcode versions are reported by users with some regularity. I suppose we could add something to the FAQ, but users don't always read the FAQ, and the first step of the first section of the installation guide already reads: "Download and install the latest version of Xcode Tools—do not install an older version from the OS X 10.4 install disk or some ports may fail to install." We should not allow users to run into this problem. Can we please modify MacPorts base to issue a fatal error and refuse to do anything unless the latest Xcode (2.4.1 on 10.4.x, 1.5.x on 10.3.x) is installed? I think this would be a good idea. When new versions of Xcode are released, we can update base as needed.
