Bas, 

Ah, I see.  That would be an issue too.

I believe that Howards build of MapScript includes SDE support, and so 
depends on some SDE DLLs.  But that is just because Howard include
SDE support ... it isn't general to Python MapScript.

This is the main mapscript DLL.  I'll leave it to Howard or others to
talk about how to deploy Howards MapScript in a cgi environment.
