Thanks much for your detail guide. I firstly built xsenserver-core, and then 
followed your instructions and there are not those package dependence issues 
when built xapi. But unfortunately, I met one make error as follow:

--- Checking for gcc... (found /usr/bin/gcc)                   ] 00283 / 02615
--- Checking for g++... (found /usr/bin/g++)
- build ocaml/xapi storage_proxy.o

Maybe I am missing something?

Thanks,
