Python v2.6 and checkPython task

[azagniotov]

Hi @xvik ,

The checkPython task is failing for me with the following error:
AttributeError: 'tuple' object has no attribute 'major'

Task :checkPython FAILED
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "<string>", line 1, in <module>
AttributeError: 'tuple' object has no attribute 'major'
FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':checkPython'.
> Python call failed: python -S -c exec("import sys;ver=sys.version_info;print(str(ver.major)+'.'+str(ver.minor)+'.'+str(ver.micro));print(sys.prefix)")

The following is the code that constructs the above command
https://github.com/xvik/gradle-use-python-plugin/blob/master/src/main/groovy/ru/vyarus/gradle/plugin/python/cmd/Python.groovy#L311

The error AttributeError: 'tuple' object has no attribute 'major' has to do with the fact that the box where I am running Gradle has Python v2.6.6 installed.

It is pretty bad, I know :( as Python v2.6 is very old, but I am afraid I am not in a position to upgrade it.

Thoughts?
