I'm able to build on MacOS with only one minor test failure. I used Apple's gcc
4.2.1, the patched gfortran from AT&T, and fink for the dependencies.

***** assert(arg (single(-1)), single(pi));
!!!!! test failed
assert (arg (single (-1)),single (pi)) expected
3.1416
but got
3.1416
values do not match
If I recall correctly, this is due to how Apple has patched gcc to handle pi
rounding for single precision.
octave:4> diff ([arg(single (-1)), single(pi)])
ans = 2.3842e-07
octave:5> eps(single(1))
ans = 1.1921e-07
