virtualenv problem on win32

[dim]

Got similar things. Don't know what is the root cause but enabling
distribute seems to work...

c:\_work\home>virtualenv --distribute pyve\openpyxl
New python executable in pyve\openpyxl\Scripts\python.exe
A globally installed setuptools was found (in c:\python25\lib\site-
packages)
Use the --no-site-packages option to use distribute in the virtualenv.
Installing
distribute............................................................................................................................................................................................done.
Installing pip.................done.
