Could you provide the entire backtrace ?
You'll get it with rake db:migrate --trace

I don't know if this is still relevant but you could try the solution provided in this blog post -> http://halyph.blogspot.com/2009/08/rails-23-migration-issues-with-m...

If it does work please update this ticket so that it can be closed.

I downloaded the older libmySQL.dll and put it in c:\xampp\ruby\bin as advised in the post mentioned by Rohit Arondekar.

Then, I merely issued the "rake db:migrate" command once more and it worked, straight away.

Thanks, Rohit and HalypH !
