eval problem in the rcfile

Hi,

  I wonder whether someone can help on this one. 

Before we run MHonArc 2.2.0, and no problem.  Bow we installed the 
V2.4.6, then the following line in the rcfile is not evaluated (should be the 
starting date of archives):
    eval $tmp = $Date{$MListOrder[0]};

we are running Perl 5.005.

 Thanks very much.

Ben
