RVM. getting git-related error while installing ruby

I'm using RVM and want to install another version of Ruby.

$ rvm install 1.9.2-head
/Users/ovsiiko/.rvm/rubies/ruby-1.9.2-head, this may take a while depending on your cpu(s)...

ruby-1.9.2-head - #fetching 
error: You have local changes to 'win32/configure.bat'; cannot switch branches.
From https://github.com/ruby/ruby
 * branch            ruby_1_9_2 -> FETCH_HEAD
error: Your local changes to 'win32/configure.bat' would be overwritten by merge.  Aborting.

There has been an error while checking out branch ruby_1_9_2.           
Halting the installation.
There has been an error fetching the ruby interpreter. Halting the installation.

Spotlight doesn't see neither win32 folders nor configure.bat files. Actualy I don't get which folder this error message refers. Already had git stash in all my recent git based projects and keep getting the same.

Any ideas how to fix this??

Thank you

P.S. I'm using MacOS X 10.6.4

UPDATE: I've uninstalled RVM then reinstalled it and tried again...

$ rvm install 1.9.2-head

Now this attempt returned error at symbian/configure.bat.

Could it be virus?

Had the same problem. Looks like there is some mess with RVM, did this command to fix it.

$ rvm cleanup repos

The git repo that rvm is complaining about is, quite obviously, one of those found under ~/.rvm, and specifically, the ruby-1.9.2-head repo.

Go to ~/.rvm/repos/ruby-1.9.2-head, stash your changes and you should be fine.
