Strange problem with pip2

[Cecil Westerhof]

There are three pip2 packages that should be updated:
    apsw (3.13.0.post1) - Latest: 3.9.2.post1 [sdist]
    mysql-utilities (1.6.4) - Latest: 1.4.3 [sdist]
    pygobject (3.22.0) - Latest: 3.27.4 [sdist]

But the strange thing is that the installed version is newer as the
new version. And when I try:
    pip2 install --upgrade apsw

I get:
    Requirement already up-to-date: apsw in /usr/lib/python2.7/dist-packages

But with pygobject the problem is even stranger, when I try to update
this, it end with:
    command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-vY4LXH/pycairo/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-40OPWv-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-vY4LXH/pycairo/


What could be happening here? And how do I solve this?
