Somethink happend when installed Profile2 by Drush

I installed it on clear installation by Drush, it printed some error and warnings to console:

Bobik-MacBook-Pro:drupal-7 Bobik$ d en profile2
The following extensions will be enabled: profile2
Do you really want to continue? (y/n): y
class_implements(): Class EntityAPIControllerExportable does not     [warning]

entity.module:173
Fatal error: Call to a member function save() on a non-object in /Users/Bobik/Sites/drupal-7/sites/all/modules/profile2/profile2.install on line 21
Drush command terminated abnormally due to an unrecoverable error.   [error]
Error: Call to a member function save() on a non-object in
/Users/Bobik/Sites/drupal-7/sites/all/modules/profile2/profile2.install,
line 21

Then I tried to disable some other modules (Profile2 is still enabled) and Drupal crashed:
Fatal error: Call to undefined function entity_load_multiple_by_name() in /Users/Bobik/Sites/drupal-7/sites/all/modules/profile2/profile2.module on line 152
This error is printed at many pages and situations (e.g. modules enable/disable, show user profile, ...).
