[thesorcerer]

The problem seems to be os.mknod, but this should be available for Python 2.5.

Or is this a Windows issue?

[Jeff Hammel]

guessing windows? haven't had a chance to look yet, though

[thesorcerer]

Any additional info I could provide or anything I should check or test?

[thesorcerer]

Any hints on this topic?

Any hints on this topic?

I haven't had a chance to look into it yet. There may be a workaround for windows, but I haven't investigated.
