Ok, well heres an update, i did succesfully build/install xen-4.1 on XCP, and got the system to reboot, issue is now
that the api seems to be completely out of whack..... and following 

plainly fails with 

omake phase1
*** omake: reading OMakefiles
*** omake: finished reading OMakefiles (0.17 sec)
- build ocaml/util util_inventory.o
+ ocamlfind ocamlopt -package stdext,log -g -dtypes -thread -warn-error +a-4-6-9-27-28-29 -ccopt -fPIC -I +ocamldoc -c util_inventory.ml
File "util_inventory.ml", line 20, characters 11-25:
Error: Unbound module Debug.Debugger
*** omake: 186/329 targets are up to date
*** omake: failed (0.23 sec, 0/14 scans, 1/15 rules, 1/313 digests)
*** omake: targets were not rebuilt because of errors:
