table node_group doesnt exist (fieldgroup enable)

Scenario:

* Clean Drupal6 install with no preexisting custom content types (just what you get out of the box).
* Core profile module setup with some categories and profile fields.
* Enabled the modules necessary to get the Profile_Migrate settings form to appear: (eg, content, content_profile, text, optionwidgets, link, date)
* Note: fieldgroup module doesn't get installed specifically.
* Select "Fieldgroup" for the import type.

Upon form submission you get an SQL error because the call to fieldgroup_groups() expects a database table (either node_groups, or content_groups, depending on the schema version) to be there, however the schema version is not set, nor does the content_group table get created during module enable — only during module install.

Table 'node_group' doesn't exist query: SELECT * FROM node_group ORDER BY weight, group_name in sites/all/modules/cck/modules/fieldgroup/fieldgroup.module on line 231.

Solution:
- Change the module_enable(array('fieldgroup')) to a drupal_install_modules() call.
- Note this requires an additional include_once.
