[Frama-c-discuss] Why/Jessie plugin version 2.22 is out

I have not taken care about that before but it looks bad: the ocaml 
compiler coming within Frama-C is ocaml 3.11.1, not 3.11.0.

I guess that you have another installation of ocaml. The PATH variable
must be set in a way you use the ocaml compiler coming within Frama-C.

That is the ocaml library coming  within Frama-C. Good.

On your system, the single command "ocaml" certainly does not work. It 
is because you use the ocaml compiler 3.11.0 (from your own ocaml 
installation) and the ocaml library 3.11.1 (coming with Frama-C). They 
are not compatible.

Setting your PATH variable for using ocaml 3.11.1 should solve your issue.
