here a first few ideas:

- Is the name of the source file in question really all lowercase (or 
are there uppercase chars inside)?
- Can you check what happens when you do the same build in the source 
tree, so with no variant_dir set?
- Looks like you are using "duplicate=0" for your variant dirs. What 
happens when you set "duplicate=1"?

Best regards,

Dirk
