I didn't think of old installations, but that was the right clue. On my 
system the package libgcrypt20 was installed (from the debian repos). 
The solution was to run first dpkg --purge --force-all libgcrypt20 
(couldn't remove it the normal way because of some dependencies). Then I 
could build GnuPG without errors. But at least one application didn't 
work, so I reinstalled libgcrypt20. Now both, GnuPG and the other 
application work and everything is fine!
