Did you remember to declare a dependency on package 'methods'? I suspect not. Please see `Writing R Extensions'.
setClass is not part of base R, and those checks are being run with base R only. I expect your package will not load when R is run with no default packages. (Quite a few people run R without package 'methods' for speed, especially on startup -- it takes about half the startup time.)
