OAuthSignatureMethod_HMAC_SHA1 not found

After disabling the LinkedIn module I started getting a 500 error from my custom reporting module that uses Google Analytics Reports. Also, I was unable to view /admin/settings/google-analytics-reports -- it was a White Screen of Death (WSOD).

Here is the error message from hitting /admin/settings/google-analytics-reports

From researching what the LinkedIn module does to use OAuth I realized that an include command for the OAuth lib file was necessary:
module_load_include('lib.php', 'oauth');

The reason that I included this line is that we shouldn't have to rely on the module weights to have this module work. The file will never be included twice because of the require_once call in module_load_include. This bug was probably a result of an undetected dependency with another module.

I will submit a patch, so please review and include in the next version of the module.

Thanks!
