 > I see occurrences of "-m64" in the build log as well, and that mix of
 32-bit and 64-bit is probably the cause of the relevant error message from
 the log:

 You're absolutely right, that's the reason. On my G5, build_arch is set to
 ppc64, and it builds fine.

 unless "build_arch" is "ppc64" in macports.conf. Atlas apparently decided
 on its own that it wanted to build 64-bit, which is a bug that should be
 fixed.

 I can do that, but does it make sense? Atlas is meant to optimize as much
 as possible the computation of matrix operations. Compiling in 32-bit
 while superior performance can be obtained by switching to 64-bit seems to
 me obviously contrary to the philosophy of the port.
