The command brew info shows the last available version of boost which is 1.7.10. This is correct.

When you run brew uninstall boost or brew remove boost, Homebrew tries to remove the last version (1.7.10). Homebrew doesn't succeed because this version is not installed. This is correct.

You have installed the formula [email protected], which is a different formula from boost. You can remove it with brew remove [email protected], or obtain information on how to use it with brew info [email protected].
