Feature request: reinstall

[parkr]

Hey, thanks for this project. I have a gem installed with C-bindings. When the Homebrew Ruby is upgraded, the absolute path to the dylib files changes:

Ignoring eventmachine-1.2.7 because its extensions are not built. Try: gem pristine eventmachine --version 1.2.7
Ignoring ffi-1.15.5 because its extensions are not built. Try: gem pristine ffi --version 1.15.5
Ignoring http_parser.rb-0.8.0 because its extensions are not built. Try: gem pristine http_parser.rb --version 0.8.0
Ignoring sassc-2.4.0 because its extensions are not built. Try: gem pristine sassc --version 2.4.0

In order to fix this, I ran brew gem uninstall jekyll && brew gem install jekyll. It would be nice to coalesce these into a single command for easier reinstallation.
