You need to make sure the directory where _CsoundVST.so or whatever is located, is identified in your PYTHONPATH environment variable. I have a feeling this may do the job.

You mean in SConstruct?  Ah, well, that gives the right solutions to 
some of the previous problems.  I now have a CsoundVST!  And it fails to 
run like this:

csound5 ./CsoundVST
Starting CsoundVST...

But the build still goes on to fail with

and so on, with screenfuls of errors.  I'll look a this in the morning.

As it happens, I can't build the DLL for csound either.

I just happened to try that.

Yes, it's _CsoundVST.so.  There I was trying to be clever and changing 
it to .dylib!  It runs happily with this command:

env OPCODEDIR=`pwd` PYTHONPATH=`pwd` ./CsoundVST

Here's the patch:
