Live version and local build not working?

[rmccue]

Trying to use the live version of the proxy (https://proxy.jmap.io/) gives a "Sign in with Google temporarily disabled for this app" error for Gmail. Using an IMAP connection gives a "Account {id} does not exist, please re-create" error.

Trying to run the project locally fails during the install instructions with an error about the libemail-address-xs-perl package. Changing this to libemail-address-perl (which appears to provide the same packages, but could be wrong) gives the following much later in the build:

Use of uninitialized value $Net::CardDAVTalk::VERSION in concatenation (.) or string at t/00-load.t line 13.

(Tested on both Debian Jessie and Ubuntu 16.04.)

Am I doing something wrong here? Was hoping to be able to test out JMAP!
