Indeed  they don't work... The simplest way is to do "ocamlfind list"
and you see that they are not recognized...

In fact, if you want it to be recognized, you need to have a META ( and
not a META.okey ). The best way to make it work is to put the lib in a
different dir ( okey goes in /usr/lib/ocaml/3.06/okey ). 

That the scheme for findlib install : 
$top_src_dir/build/{okey,configwin,options...}/META + *.cma *.cmxa *.cmi
+ pa_*.cma 

( the last statement is funny, but it is a lot more easy to manage
camlp4 syntax with META, since there is a special
syntax(preprocessor,archive) = pa_ioXML.cma
syntax(preprocessor,native) = pa_ioXML.cma which is used to understand 
the camlp4 syntax... After that you just need to compile wiht

ocamlfind ocamlc -package ioxml -syntax camlp4r -c my_file.ml

)

I don't like ocamlfind guess... Writing a META is a five lines jobs...
Not so hard ( comparable to all the pkg-config scheme ).
