it seems the tests definately improve things...

[root@localhost ~]# cat testfile.ml
print_string "hello"
[root@localhost ~]# ocamlfind ocamlc -o test -thread -package xeneventchn -
linkpkg -g testfile.ml
[root@localhost ~]# ./test
Fatal error: cannot load shared library dllxeneventchn_stubs
Reason: dllxeneventchn_stubs.so: cannot open shared object file: No such file 
or 
directory


(i have no idea if i need to ./test execute this, or if this is normal 
behavior)


one more thing:

[root@localhost ~]# cat /usr/lib64/ocaml/xenlight/META
version = "4.1"
description = "Xen Toolstack Library"
archive(byte) = "xl.cma"
archive(native) = "xl.cmxa"

it should be xenlight.cma

(the others are fine)
