I myself use AOKP, although I believe the permission management feature was cherry-picked from Cyanogen, and Google searches seem to verify the functionality exists.

On AOKP, you have to enable it by going into System Settings -> Permissions, which will then let you manage your apps.

Cyanogen uses a similar system[1], you'll need to navigate to CyanogenMod Settings, then Permissions, and finally Enable Management. After that, permissions can be enabled or disabled through the Settings -> Applications -> Manage Applications menu.

[1]Those instructions were pulled from a Google search, as I don't run Cyanogen myself currently. They may be old/incorrect/etc. Good luck.
