Review and Bump Formulae revision numbers

[drbenmorgan]

Please follow the general troubleshooting steps first:

• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [x] Confirmed this is a problem with specific formulae and not brew? If it's a general brew problem please file this issue at https://github.com/supernemo-dbd/brew/issues/new

Latest upstream updates to GSL changed ABI versions. Review dependent packages, and bump revisions to trigger rebuilds on updates.
