See #376458: project_page_link_alter() is broken for the changes to hook_project_page_link_alter(). Basically the parameters have been flipped to match the implementation of hook_link_alter().
In case the patch does not attach correctly, it can be viewed at http://drupal.org/files/376458-versioncontrol-project-page-link-alter-HE...

jpetso commentedHeh... nice to know that those arguments were indeed switched for the D6 port. (I had feared compatibility would prevail over D6 style conformance.)
That makes versioncontrol_project's port complete, I guess. Thanks for the patch, committed to HEAD.
