Sure! At the top of the file in the constructor is where we set 2 variables that are checked to see if the component is installed:
$this->_componentFolder = JPATH_SITE . DS . 'components' . DS . 'com_community';
$this->_componentFile = 'libraries' . DS . 'core.php';
Change those to something like below, which are directories that are guaranteed to exist in Joomla:
$this->_componentFolder = JPATH_SITE;
$this->_componentFile = JPATH_SITE.'/index.php';
You can use your own extensions file's if you want to do a 'real' check.
Let me know if you have any questions. The profile import stuff, on the simplest level, is pretty easy. Just a few functions. JomSocial and the plugins we create are pretty complex as they've grown over the last 2 years. We're planning to revise our profile plugin system with the next major (v2.0) release to simplify the plugin structure again and pull more functionality into the base classes.
Good luck,
Alex
