Install error on 4.4.5

[e_mason]

Been bumping into an install error on 4.4.5 on new sites... the installation screen loads and checks requirements, but the install screen just goes to a white screen and never makes it to the "successfully installed" screen.

The php log shows the following error: PHP Fatal error:   Call to undefined function _block_rehash() in /home/afp/www/conference/sites/all/modules/civicrm/drupal/civicrm.module on line 685

If I install 4.4.4 on the same site (after cleaning the database, removing civicrm.settings.php) the install goes as expected.  I can even upgrade to 4.4.5 (and run the upgrade script) without problem.

Drupal 7.28, Panopoly distro on civihosting.

Just to follow up - I don't think this a CiviCRM issue per se as 4.4.5 does install nicely onto Drupal 7.28, but a warning that using a Drupal distribution other than Core can result in some unexpected results.

...and a resolution.

The _block_rehash() function is called from the block module.  Panopoly has this disabled ... simply enabling the block module before running the CiviCRM installer seems to clear up the problem!

Should be an easy fix. Thanks for reporting.
