Brad,

That error-message is due to not finding the "magic" value in the right spot of 
the product-queue. We've never seen this happen and we've run the LDM on many 
32- and 64-bit systems. Could the product-queue library be trying to open a 
product-queue that was created in a different bit-length environment? What 
happens if you recreate the product-queue?

A 32-bit GDBM library is necessary for the the DBFILE action of pqact(1). The 
fact that it was necessary on a 64-bit system indicates that the LDM wasn't 
built using a 64-bit programming environment. Something's wrong. Would you 
please send me the outputs of the configure(1) script and the "make" command.
