# From bash, set the engine on all tables in a database to InnoDB

Fix for rvm install 1.8.7 with glibc 2.14
glibc 2.14 breaks the install process for ruby 1.8.7 and ree 1.8.7.
Fix for ruby 1.8.7 install with rvm:
1. Run `rvm install ruby-1.8.7-p334`
2. Wait for it to fail.
3. Fix the broken files with:
cd ~/.rvm/src/ree-1.8.7-2011.03/source/ext/dl
rm callback.func
touch callback.func
ruby mkcallback.rb >> callback.func
