Has anyone been successful with running the 3.2 version of ActiveRecord with SQLite3 (or SQL Server)? (Note: the 2.3.8 version works fine). It seems that 3.2 support for EXPLAIN may be causing a ''no such file to load -- active_record/relation/explain. I also ran a version of my app on MRI with ActiveRecord 3.2 and it worked just fine.
