Based on your Facebook comments, you're also having issues with zef. Were you able to fix it? Does it still show that error if you try to install another module? Can you create directory C:\Users\winklest\.zef\store\p6c\ manually and see if that makes it happy?
I don't have any issues with zef on my box (though it's not creating `.zef` in C:\Users\username\.zef but in my %HOMESHARE% that's located on a network drive). >panda install zef ==> Fetching zef ==> Building zef ==> Testing zef t/\00-load.t ........... ok t/\identity.t .......... ok t/\utils-filesystem.t .. ok All tests successful.
