Installing new testbed of  Drupal 7.0 + CiviCRM 4.0b1. Drupal works great, but CiviCRM fails with "HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request."

I found the following in the apache error log:

I've encountered the same error with installs of Drupal 7 and CiviCRM 4.0 beta2 as well as beta3. If this is a configuration error, following the instructions posted will not help. It looks more like CiviCRM not handling some environments as well as others.

My environment is MAMP 1.9.5 on OSX 10.6.7, PHP 5.3.5, MySQL 5.5.9. I performed a clean install of Drupal and CiviCRM each time and wiped the databases. Drupal works fine, but I receive the following error whenever I access a CiviCRM page:

DRUPAL_ROOT should be resolving to /Applications/MAMP/htdocs

Forum and google searches turn up nothing on this error or include path errors in general. Also the lack of a stacktrace option makes it difficult to debug these issues. Line 56 in BAO/Website.php is calling a constructor in DAO/Website.php and so on. There is no file in the CiviCRM module directory or the settings.php that defines DRUPAL_ROOT, so I'm assuming it is derived somewhere during bootstrap.

Someone with some experience needs to look at this as the available information is of no use in resolving this issue.
Thanks in advance.

is it the exact same error INCLUDING line number? there is no mention of DRUPAL_ROOT in that file.

Also do u have an error handler page which is potentially throwing that error?

Turning off XCache (MAMP > Preferences > PHP > Cache) seems to have fixed the issue for me.
