How about installing a package with  /usr/bin/ocamlc -3.09.3,  
/usr/bin/ocamlopt-3.09.3 , etc, another one with /usr/bin/ocamlc-3.10.2, 
/usr/bin/ocamlopt-3.10.2, etc.  and usin alternatives to switch among 
the two by doing

ln -s  /usr/bin/ocamlc -3.09.3  /usr/bin/ocamlc (and so on) or 
ln -s  /usr/bin/ocamlc-3.10.2 /usr/bin/ocamlc 

?
