Thanks to you both for your explanations. Updating everything as 
suggested by James did work as well.

However, I guess as the annotation packages being used by gcrma() are 
loaded in a dynamic manner and packages for other species have different 
versions (?) this static dependency check via the DESCRIPTION file won't 
work?

In an application one would try to catch the problem at run time in 
order to give the user a meaningful error message. Especially, if a new 
version depends on a feature not available in previous versions. But I 
don't know this is worth the effort here.

Ciao,
