 =head1 DESCRIPTION
 
 If you're using this driver than your version of Sybase does not support
-placeholders. You can check with:
+placeholders, or your version of L<DBD::Sybase> was compiled with FreeTDS rather
+than the Sybase OpenClient libraries. You can check with:
 
   $dbh->{syb_dynamic_supported}
 
+To see if you are using FreeTDS, run:
+
+  perl -MDBI -le 'my $dbh = DBI->connect($dsn, $user, $pass); print $dbh->{syb_oc_version}'
+
+You will get a warning on startup if you're using FreeTDS in any case.
+
 You can also enable this driver explicitly using:
 
   my $schema = SchemaClass->clone;
