Call to undefined: taxonomy_get_vocabularies()

Drupal: 6.10
translation_table: 6.x-1.0-beta1
PHP: 5.2.0-8+etch13

going to admin/build/translate/table and admin/build/translate/table gives me this:

Fatal error: Call to undefined function taxonomy_get_vocabularies() in /www/ahjumeister/html/sites/all/modules/translation_table/translation_table.module on line 229

admin/build/translate/table/menu

works fine.

taxonomy_get_vocabularies() is defined in modules/taxonomy/taxonomy.module

Also I think admin/build/translate/table is not best place where to put the translation interface.
Its quite hard to find it. I had to read the source to find it.
I would had it as tab under "Translate interface" (admin/build/translate) or something like his.
