update to 1.2 fails on OS X 10.7.3

[socketbox]

I'm having difficulty updating pythonbrew 1.1 to 1.2. Here's the error I received:

sb [ ~ ]$ pythonbrew update

I thought this might be related to the default system installation of Python 2.7 in OS X based upon what I read here so I installed 2.7.3 from the python.org site, and ran the update script to update my path.

After verifying that python version 2.7.3 was called by default in the shell, i ran pythonbrew update again. However, pythonbrew persists in using the interpreter under /System. Despite having looked at the code under ~/.pythonbrew, I'm unable to determine how to change this behavior.

On Linux, too. It seems like it tries to check if the file is a tarfile before downloading it. (That's because first test on content_type is failing)

[dahjelle]

I'm not sure if it is equivalent, but I was able to do a pythonbrew update --master to update via git. It now reports version 1.2, though I'm not sure if the master branch here on github tracks the release versions exactly or not.

@dahjelle : it's not the same. In one case a tar.gz archive is downloaded, in the other, it's over git.

Results in the same error. Using the --master flag seems to help, oddly. Though that, too, seems buggy.
