Hmm... Sounds like it's either botched or missing the include path.
Can't find unit WORKBENCH
Sounds like it's looking for a file and not finding it. Check it out with SnoopDOS and see if you can see where it's expecting to find the WORKBENCH unit. (or check if you even HAVE a WORKBENCH unit, or if it's part of an API that is needed but not included in the basic install.)
