Hi,

This bug seems to have nothing to do with camlp4/5. I've seen this bug 
twice before, with two different version of OCaml (3.09.3 and 3.09.2 
namely), but always Coq 8.1pl2. It's rare, and I have no clue why they 
occur.

One solution is to move to the trunk version of Coq (whose Makefile has 
been reengineered, and is far less surprising).

If you insist on keeping 8.1pl2, then here is a way to work around it :
First do a :
  make world
when it stops, do :
  make parsing/q_constr.cmo
to build the missing file, then do :
  make worldnodep

Which should build everything but not clean the installation (as make 
world do before building the dependencies).
