But with this line of reasoning, plexer.{o,cmx} should not be
installed either, shouln't it?

   because these are *camlp4* modules, camlp4 loads bytecode
   (only) dynamically from a single cmo file (only).

No, for me it was like that:
- first I didn't know, there is library with these modules 
  (how to find out what library contains a given module without
  grepping through the build log?)
- linking gramlib does not work, because the module is not
  explicitely referenced (only during runtime the program does a
  dynlink on something else that needs the given module)

I could fix that with adding an artificial reference like

module XXX = Plexer


(I could still imagine some camlp4 application szenario, where
you need to use -linkall, but don't want to link all of
gramlib.cma. Then you would need the cmo itself, right? However,
this was not the case in my application.)
