in reply to cpanm installation problems with mixed case files

I have no idea if this will help you or not, but the April 2018 update of Windows 10 included the ability to make directories case sensitive on a directory by directory basis. Example command: fsutil.exe file setCaseSensitiveInfo C:\folder enable makes "folder" case sensitive. As a caveat, I have never used this feature. An article from howtogeek is here: how-to-enable-case-sensitive-folders-on-windows-10
