If you are seeing this error I am getting an error upon running ./install_amp from a fresh svn source.
It’s complaining about a non-existent MySQL column being addressed:

Please Reload Asterisk by browsing your server.

Then you need to issue the following from the command line ./install_amp –force-version 2.1.1
