If you can log in to the server, write a short program like: 
dbmopen(%FOO, "hlag", 0666) || die;

And then run it with the debugger. Step THROUGH the dbmopen and you'll see things like: 
4:      our @ISA = qw(NDBM_File DB_File GDBM_File SDBM_File ODBM_File)
+ unless @ISA;
nyDBM_File::(/usr/local/lib/perl5/5.6.0/AnyDBM_File.pm:6):
6:      my $mod;
nyDBM_File::(/usr/local/lib/perl5/5.6.0/AnyDBM_File.pm:7):
7:      for $mod (@ISA) {
nyDBM_File::(/usr/local/lib/perl5/5.6.0/AnyDBM_File.pm:8):
8:          if (eval "require $mod") {

AnyDBM is going to step through that @ISA array to find which database is available. The one where the eval works, is the one that you're using.

There are more hackish ways of doing this like looking at %INC after the dbmopen to see what got brought in successfully.
