2. open win32-lanman.ppd by a text editor, change version 5.8.8 to 5.10.

That would allow the module to install, but Win32::Lanman would still be unusable (because of binary incompatibility). If Win32::Lanman were a pure perl module, then there may be no problems with that suggestion - but, unfortunately, Win32::Lanman contains code that needs to be compiled and is not pure perl .

If there's a ppm package for it at the trouchelle repo, then that would be the best shot.
Although Jan was initially going to pick up this module, he was deterred by the restrictive GPL license. I don't know if anyone is doing anything with it.

Cheers,
