Missing Include

I installed the module and when going through the config screens I found the following on the search config screen:

Warning: include_once(/home/website/web/modules/taxonomy/taxonomy.admin.inc): failed to open stream: No such file or directory in include_once() (line 12 of modules/contrib/taxonomy_manager/taxonomy_manager.admin.inc).

Is that require something left over from the conversion?
