I wonder why

gem install sqlite3-ruby

will fail on a PC with Vista?

when i do a search on google for sqlite3-ruby, I see that 1.2.4 was  
actually done in August 2008. So does that mean for 8 months (from  
2008-08 to 2009-04), it was breaking all people using a PC?

turns out that it needs to be

gem install -v1.2.3 sqlite3-ruby

can’t it simply show a message saying you need 1.2.3 for a PC? or show a  
selection list like on [http://agilo.us/2009/03/15/rails-on-windows/](http://agilo.us/2009/03/15/rails-on-windows/) ?

that’s kind of weird…

this is the error message for “gem install sqlite3-ruby”:
