According to Tom Dye:

Oops! Another lesson learned the hard way! But it seems as if I'll have to wait for the next beta, since neither the 971001 beta nor the patched version will compile the code I have. Or could you recommend a previous beta or other version that I might use in the interim?

You can try previous beta versions which do not check whether the head in the interface module matches that in the implementation module.

Hope this helps,

Peter
