Thank you, Dario.

For exactly this, I get the correct

* checking package dependencies ... NOTE
Vorgeschlagenes, aber nicht zur Überprüfung verfügbares Paket: aPackageNotFoundTypically

(I changed the line in 'DESCRIPTION' to
Suggests: aPackageNotFoundTypically

which is exactly the 'de' translation for
the one I mentioned earlier in this thread:
      c(gettextf("Package suggested but not available for checking: %s", bad),
I'm appending the slightly modified version of your testPackage.tar.gz
which only gives one 'NOTE' (see above) and no warning in  
'R CMD check'...
aah .. but when I rerun it as "Joe Average" user, instead of
myself, I get your

* checking package dependencies ... ERROR
Package required but not available: aPackageNotFoundTypically

.... dig dig...
I see, it's because in a file I source in ~/.bashrc I have
   export _R_CHECK_FORCE_SUGGESTS_=false
which of course is what Brian and Simon alluded to when they
told you you could turn off the behavior ...

Ok, so we have finally converged....

I think I agree with Hervé: If a user has not set the
magic environment variable he should get an ERROR instead of a NOTE
but the error *message* should be the correct one.

Ok, so thanks to Dario and Herve for persevering...
