GemBuilder on VisualWorks 7.9.1 error message

GBS C interface failed to initialize.

Make sure at least one of the file(s) libgcilnk.dll libgcirpc.dll  exists and is accessible.

The error message was: Could not load library.

I have no idea where to find the dlls.

What I want to do: Upgrade an existing GemStone/VisualWorks application to VisualWorks 7.9.1
