Looks like we found the problem:

'PERL_MM_OPT' => 'INSTALL_BASE=C:\\Users\\U0159691\\perl5',

[download]
  1. right-click "My Computer" and select "Properties"
  2. find the "Advanced" system settings (tab along the top or option at the left)
  3. click "Environment Variables"
  4. find the PERL_MM_OPT variable and delete it
  5. reboot since hey it's Windows
  6. try the installation via cpan or cpanm again

If you can't find it, it's likely being set in some custom config / startup file somewhere, which might be a little harder to track down unless you know where it is.

As a side note, you could remove C:\Users\U0159691\perl5\bin from your PATH while you're at it.
