Distro - Ubuntu 12.04.3 LTS (Precise),
Kernel - 3.13.2
Xen version - 4.4 unstable (custom build)
yajl older version: 1.0.12-2
# aptitude versions libyajl-dev
Package libyajl-dev:
pi  1.0.12-2                    precise                         500
Package libyajl-dev:i386:
p   1.0.12-2                    precise                         500

Latest yajl version available: 2.0.1

There is some change in the yajl code between version 1 and 2, which
prevents the tools, specifically libxl from compiling.

Thanks,
Aastha.
