Issue with Parse Library Import

I have followed along to the point where we add our Parse keys in the app delegate, and run. Unfortunately though when I go to run, I get the following errors that I don't quite understand:

Undefined symbols for architecture i386:

"OBJC_CLASS$BFExecutor", referenced from: objc-class-ref in Parse(BFTask+Private.o) l_OBJC$CATEGORY_BFExecutor$Background in Parse(BFTask+Private.o) "_OBJC_CLASS$BFTask", referenced from: objc-class-ref in Parse(PFUser.o) objc-class-ref in Parse(PFFile.o) objc-class-ref in Parse(PFNetworkCommandRunner.o) objc-class-ref in Parse(PFObject.o) objc-class-ref in Parse(PFPush.o) objc-class-ref in Parse(PFRetryingCommandRunner.o) l_OBJC$CATEGORY_BFTask$Private in Parse(BFTask+Private.o) ...

Any suggestions?

Thanks!
