The mailing list for listmasters using Sympa

[address@concealed]

I've just installed Sympa 3.3.5 on a RedHat 7.2 server. However, when I run 
sympa.pl I get the error message "Key 'compare' not associated with a code 
reference at
/home/sympa/bin/List.pm line 918". 

I have version 1.805 of DB_File installed. I found the suggested solution to 
this problem in the mailing list archive, but the patch for List.pm seems to 
refer to a beta version of Sympa, not to the current 3.3.5 version. I also 
tried to install an older version of DB_File but each time I got the 
following error message, at make time:

DB_File.xs:1369: warning: passing arg 2 of pointer to function from 
incompatible pointer type
DB_File.xs:1369: incompatible type for argument 4 of indirect function call
DB_File.xs:1369: too few arguments to function

Is there a beta version already available that includes the patched List.pm 
file? If not, how can I go back to an older version of DB_File? Any 
suggestions or ideas will be greatly appreciated.
