I'm wary of php enought not to know wheter this is #8 but the ZIP extension seems missing.

I'm using composer and it fetches stuff like

• Installing phpunit/phpunit (3.7.31)
  Downloading: 100%
  Failed to download phpunit/phpunit from dist: Could not decompress the archive, enable the PHP zip extension.
  A php.ini file does not exist. You will have to create one.
  Now trying to download from source
  • Installing phpunit/phpunit (3.7.31)
    Cloning d24e9877331039582497052cc3c4d9f465b88210

Guessing from execution times it does download twice.
