When was the "use lib" bug fixed?

I have a Build.PL that says:

     use lib "inc";
     use Local::Module::Build;

     my $builder = Local::Module::Build->new(...);

And there's inc/Local/Module/Build.pm.

This has worked for some time, "inc" gets added to ./Build.  But it appears 
not to with certain versions of Module::Build, I'm trying to track down what. 
  Build can't find Local::Module::Build, its not in its @INC.

Any idea when this bug was fixed so I can add in the proper MB dependency?
