OK -- tested on Mac OS-X 10.6, Intel, 32 bit Python 2.6.6

1) How necessary is scipy as a dependency? It'd be nice to have these 
for numpy-only stuff. As  a rule, Scipy is way too inter-meshed as it is 
-- I'd love to have more packages that you could easily install and use 
without the whole scipy package.

-- off to get scipy installed on this system --

Running unit tests for bottleneck
NumPy version 1.5.1
NumPy is installed in 
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/numpy
Python version 2.6.6 (r266:84374, Aug 31 2010, 11:00:51) [GCC 4.0.1

WOW! a LOT of these warnings:

Warning: invalid value encountered in divide
(and similar)

But:

Ran 10 tests in 14.709s

OK
Out[7]: <nose.result.TextTestResult run=10 errors=0 failures=0>

So -- looking good!
