python error in opencv installation

I am attempting to install the opencv library in Linux and I get the following error in a log generated by a python script:

Traceback (most recent call last):
  File "/tmcleod/opencv-2.4.4/modules/java/generator/gen_javadoc.py", line 257, in ?
    import hdr_parser
  File "/tmcleod/opencv-2.4.4/modules/java/generator/../../python/src2/hdr_parser.py", line 641
    decl[1] = ": " + ", ".join([b if "::" in b else self.get_dotted_name(b).replace(".","::") for b in bases])
                                   ^
SyntaxError: invalid syntax

Here is the command in the makefile that is causing the error:

cd /tmcleod/opencv-2.4.4/release/modules/java && /usr/bin/python2 /tmcleod/opencv-2.4.4/modules/java/generator/gen_javadoc.py --modules core,imgproc,objdetect,features2d,video,highgui,ml,calib3d,photo,contrib /tmcleod/opencv-2.4.4/modules/java/generator/src/java /tmcleod/opencv-2.4.4/release/modules/java 2>"/tmcleod/opencv-2.4.4/release/modules/java/get_javadoc_errors.log"

I do not know why I need to generate java docs on the installation of a C++ library, but the issue is causing the build to fail. Any help appreciated.

The problem here was that cmake was finding an older version (2.4) of the python executable that did not understand this construct. The workaround is to pass cmake a path to python. From opencv extract directory:

$ mkdir release
$ cd release
$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=./build -D PYTHON_EXECUTABLE=/tmcleod/Python-2.7.3/python ..
$ make
$ make install
