Description of problem:
While building packages for el5, glusterfind python scripts throw the following syntax error:

Version-Release number of selected component (if applicable):
mainline

How reproducible:
100%

Steps to Reproduce:
1. checkout the master branch
2. build el5 rpms in mock
    $ make clean 
    $ rm -f *.tar.gz *.rpm
    $ ./autogen.sh && ./configure && make dist
    $ rpmbuild -ts --define "_srcrpmdir $PWD" *.tar.gz
    $ mock -r epel-5-x86_64 *.src.rpm


Actual results:
Packages are created, but the build.log (in the results directory) contains the syntax error.

Expected results:
No syntax error in the build logs.

Additional info:
If glusterfind is not expected to work on el5, it should not get packaged. If that is the case, assign the bug to me with a note and I'll take care of it.
