What's bizarre is that that's not a valid egg filename; they must 
have renamed it at some point.

The filename is invalid in two ways: first, it has a '.' between the 
version and the Python version (it should be a '-') and second, 
'winxp32' is not a valid platform name.

I would suggest contacting the PyOpenSSL maintainers to find out why 
they have renamed it in this fashion; .egg files should never be 
renamed under any circumstances.

(I'm actually surprised that easy_install is recognizing it at all, 
but basically it appears to be treating it as if it's a 
non-platform-specific egg.  That's arguably a bug.)


>zipimport.ZipImportError: not a Zip file

This part is an expected failure with a --dry-run.  It perhaps could 
be fixed, but the problem is that with --dry-run on, the egg is not 
moved to the target directory, so when it tries to create a 
Distribution object for the installed egg, it fails.  This has 
nothing to do with the version problem - you will probably see this 
occur at the end of any --dry-run install, unless an 
identically-named egg was was already present.
