After I install the xen-devel.rpm, I pass the xen headers check without
modifying the
Xen header path in build-rr.sh.
Even after I make sure the existence of the header file rump_curlwp.h,
the building process still goes wrong.
The error is showed as below:

```
I tried to found the linux_blkio.d file to add the path of rump_curlwp.h,
however it seems that the linux_blkio.d is generated automatically.
And also the path of rump_curlwp.h is not included in the command described
above.
