Heroku deployment fails every time (no replies)

Hello,

I have tried to install Piwik on Heroku and bumped into two problems:


Problem #1:

Push is going fine, until I get

emote:
remote: Compressing source files... done.
remote: Building source:
remote:
remote: Build stream timed out, reverting to polling....
remote:
remote: ! Timeout reached polling for results.
remote:
To https://git.heroku.com/*****piwik.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/***piwik.git'


Anyone solved this problem? Are there too many files or something?


Problem #2:

Even though push in problem #1 fails, Piwik seems to be in Heroku. When running the installation, it complains about:

The mbstring extension is required to handle multibyte characters in the User interface and API responses. Also please check that mbstring.func_overload is set to "0" in php.ini.

AND

always_populate_raw_post_data=-1
To prevent some critical issue, you must set the following in your php.ini file: always_populate_raw_post_data=-1
After making this change, restart your web server.



**
Tried to correct these by setting those to config/global.ini.php and pushed, but then getting again the problem #1. And no change for problem #2.




Anyone helping me?
