With ocamlobjinfo, you get, on the .cma of camlpdf:

  Unit name: Unzip
  Interfaces imported:
	9c9fa5f11e2d6992c427dde4d1168489	Array
	3da72249626c7db769beafc97036cb4f	Char

	b372d9bd060c60cc1e3bc9fa72c6a310	Istring
	654e09b87b678c68611416c15336b53f	Io
	ee2a3220e38a4350c5bc131ce9f3f6ce	Hashtbl
  Uses unsafe features: no

and on the .cma of extlib:

  Unit name: Unzip
  Interfaces imported:
        9c9fa5f11e2d6992c427dde4d1168489        Array
        b941185daa9d8cdf275d1b70640a65c6        IO
        3da72249626c7db769beafc97036cb4f        Char
        88cb1505c8bdf9a4dcd2cdf3452732b4        Pervasives
        ecc403546c1c50056801131811c39017        String
        45838fbf4d9f26e9bb96cb6f3691849b        Enum
        8c4bf5f5cada33735dcb10f487c95bff        Unzip
        ee2a3220e38a4350c5bc131ce9f3f6ce        Hashtbl
  Uses unsafe features: no

but, to my surprise, there is no Unzip module in 
/usr/lib/ocaml/3.11.0/zip/zip.cma...

So I do not really know how to determine which of the Unzip modules (in 
camlpdf or in extlib) is "the right one". But it seems to me that 
camlpdf's Unzip is built against Io and Istring, which might account for 
the discrepancy.
