Don't worry no offense taken. I didn't request a merge for the following 
commit (that extract coqide and its dependencies to another package and 
that would have saved your day) because it is more a hack than a real 
solution. I was looking for a better solution because I'm also 
frustrated ( today I have the pleasure to do opam upgrade
   - recompile camlp5.6.07 [upstream changes]
   - recompile coq.8.4pl1 [use camlp5]

Leaf project (in the dependency graph) like Frama-C are less a problem 
and since other project can depend on their libraries and binary 
(ex:Why2) its good to have them in opam. Moreover Frama-C takes only 
2min to compile.
