version 6.7 compiled warnings

[tmv2]

Warning 1 'OpenDentBusiness.ClaimProc' overrides Object.Equals(object o) but does not override Object.GetHashCode() C:\opendental\svn\opendental6.7\OpenDentBusiness\TableTypes\ClaimProc.cs 7 15 OpenDentBusiness
Warning 2 Could not resolve this reference. Could not locate the assembly "Microsoft.VisualBasic.PowerPacks.Vs, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. OpenDental
Warning 3 The referenced component 'Microsoft.VisualBasic.PowerPacks.Vs' could not be found.

Should I be concerned? From a Java background, I know Warning 1 will cause problem with sorting or using ClaimProc as a key in a Map. I don't what issue I will run into with Warning 2/3.
