Thomas,

I continue to encounter a failure in data.cc.

 121 >>>>> processing 
/Users/bpabbott/Development/mercurial/local_clone/src/data.cc
 122   ***** assert(log2(complex(0,Inf)), Inf + log2(i));
 123 !!!!! test failed
 124 assert (log2 (complex (0, Inf)),Inf + log2 (i)) expected
 125 Inf + 2.266i
 126 but got
 127 Inf - NaNi
 128 NaNs don't match

Using Apple's gcc-4.2.1, I've not been able to resolve this by changing the
