thank you very much for the explanation rainer! 

what i failed to understand is that macports now ship bash 5.1.8 which is obviously >= 5.0.
i googled for any more information about this incompatibility without success.
moreover, i found out the bashdb fails to build at config level because of a case statement.
then i locally patched Portfile and created a patch for configure file (attached) and everything worked.

yet i admit i often use bashdb to debug simply shell-scripts and have no idea if this incompatibility lays on more complex scripts.
