Reading the COPYING file I noticed that libgit2 is GPL2-only (no versions after 2) licensed. It includes Apache 2.0 licensed code according to the COPYING file. The GPL2-only is NOT compatible with the Apache 2.0 license.

Quote from http://www.apache.org/licenses/GPL-compatibility.html:

Despite our best efforts, the FSF has never considered the Apache License to be compatible with GPL version 2, citing the
patent termination and indemnification provisions as restrictions not present in the older GPL license.

I would recommend to relicense libgit2 to GPL2+ that would it becomes compatible with the Apache 2.0 license.

The software I am writing which wants to make use of libgit2 also needs Apache 2.0 compatibility, if this issue doesn't get resolved I can not use libgit2 for Smuxi.
