upgrading ocaml requires rebuild of all ocaml packages. apparently this is because of the static linking between libraries. 

to get the packages rebuilt in one run, special care must be taken to send the requests in certain order. 

first ask someone with proper rights to remove current ocaml from builders 

<file>poldek -ev --noask ocaml ocaml-runtime
</file>
then start sending ;-) 


  - ocaml 
  - ocaml-lablgl 
  - ocaml-lablgtk 
  - ocaml-findlib 
  - ocaml-postgres 
  - ocaml-mysql 
  - ocaml-pcre 
  - ocaml-equeue 
  - ocaml-net 
  - ocaml-xstr 
  - ocaml-wlex 
  - ocaml-netclient 
  - ocaml-stew 
  - ocaml-pxp 
the rest of packages need to be rebuild can be queried with this command 

<file>$ ac-requires ocaml-runtime
$ ac-requires ocaml
</file>
