Hello…

Is there any word on when the eventmachine 0.12.2 and sqlite3-ruby 1.2.4  
gems are going to be fixed to work when updating gems on a Windows (xp)  
system? Doing a ‘gem update’ will cause errors for both, which causes  
the rest of the updated to installed gems to not be updated. I’ve been  
using a workaround script that skips the errors and continues updating,  
but I’d be nice to get updated gems.

(I’m also seeing a strange thing with the webby gem - when doing a ‘gem  
outdated’, I see:

webby (0.9.3 \< 0.9.3)

and updating causes the “new” version to be installed, but gem outdated  
still gives that message.)

Here are the errors for sqlite3-ruby and eventmachine, for what it’s  
worth…

eventmachine:
