Won't build on Windows

[sp]

Installed Python 2.7.4 (first tried 64-bit and then 32-bit - same error both times). Here is what I got:

C:\allmydata-tahoe-1.10.0>c:\Python27\python.exe setup.py build Traceback (most recent call last):

File "setup.py", line 73, in <module>

egg = os.path.realpath(glob.glob('setuptools-*.egg')[0])

Previously I was able to build but had other problems (I remember the first error was something like "dep missing").
