well, something like:
 
@AnyDBM_File::ISA = {
    -lgdbm => "GDBM_File",
    -ldb   => "DB_File",
    -lndbm => "NDBM_File",
}->{$DBM_LIB};

dbmopen ...;
or
tie %DB, "AnyDBM_File", ...

would do the trick, the question is, how does dbmmanage know what
$DBM_LIB is.  

Based on the order in your patch, this should work:

use Config;

for (qw(-ldb -lndbm -lgdbm)) {
    $DBM_LIB = $1, last if $Config{libs} =~ /($_)/;
}

Or, you could have Configure modify dbmmanage I suppose (ick).
