Ubuntu 12.04 PPA fails compiling Expressions

I am using Ubuntu 12.04, I recently updated via PPA to dolfin 1.2.0

My code does not work when I try to use "Expression"

In [1]: from dolfin import *
In [2]: mesh = UnitCubeMesh(10,10,10)
In [3]: V=FunctionSpace(mesh,"CG",2)
In [4]: E=Expression('x[0]>12?1:2')
Calling DOLFIN just-in-time (JIT) compiler, this may take some time.
In instant.recompile: The module did not compile with command 'cmake -DDEBUG=TRUE . ', see '/home/cchintaluri/.instant/error/dolfin_compile_code_d921ff1f9a69752d5ac5a72c2e599b20/compile.log'
.
.
In [5]: dolfin.__version__
Out[5]: '1.2.0'

In [6]: dolfin.has_cgal()
Out[6]: True

The complile.log reads thus:

CMake Error at CMakeLists.txt:11 (INCLUDE):
  include called with wrong number of arguments. Include only takes one
  file.
