Building GnuPG from the GIT repositories

Note that this is only for developers and there is no guarantee that a version will work. Do not post a bug report etc., the developers are likely aware of it.

In general follow the instructions in the README.GIT files
You may not use the latest automake version because they have a regression against former versions. README.GIT gives hints on how to use older versions.
Here is a script to build GnuPG and all its related libraries: https://github.com/Wikinaut/utils/wiki#wiki-How_to_compile_GnuPG_gpg_from_the_github_sources
