I've talked with upstream. Here is part of his answer:

> I don't know much about packaging Ocaml modules, but I think the solution is for me to rename Unzip and Io to PDFUnzip and PDFUnzipIo in the next release. How does that sound? 

Moreover, it seems that unzip provides some functionality that is not 
provided by extlib's unzip module. But this may also be functionalities 
that have been squashed out of camlpdf when requiring camlpdf to build 
against camlzip...

I guess that the simplest solution would be to let upstream change the 
module names upstream.

In the long run, the "right thing" would perhaps be to include an Unzip 
module in camlzip. This is, IMHO, where Unzip should belong.

Best regards,
