This is a new check in R-devel. The NEWS say:

> R CMD check etc now warn when a package exports non-existing S4 
> classes or methods, also in case of no "methods" presence

In your case, the NAMESPACE contains

> exportClasses("bujar")
> exportMethods("show")

but the package neither defines an S4 class "bujar" nor methods for the
S4 generic "show". You should remove these two lines from your NAMESPACE.

Best regards,
