Do you really mean to say you want to update from a 2.7 installation to a 2.7 installation from the svn repo? In that case you don't have to removing the existing installation (or even upgrade site-packages), unless you change the architectures (switch to/from a universal build, or to a different kind of universal build) If you upgrade from 2.6 to 2.7 you don't have to remove the 2.6 install, 2.6 and 2.7 can be used side-by-side (both for unix and framework installs). > I guess there is just a list of files to remove but I couldn't find a list. That depends on the type of install. For a framework install (python in /Library/Framework/Python.framework) you need to remove "/Library/Frameworks/Python.framework/Versions/2.7" and "/Applications/Python 2.7". Depending on how you installed and with what options there may also be symlinks in /usr/local/bin. Note that there are two binary installers for 2.7 on the website: one containing 32-bit binaries that work on OSX 10.3.9 or later and one containing ppc, i386 and x86_64 and works on OSX 10.5 and later. The latter has two features that might cause surprises: Tkinter doesn't work in 64-bit mode because the system version of Tk 8.4 doesn't support that and furthermore the readline extension is linked to libedit instead of the real readline. The latter means that the configuration for key-bindings uses a different syntax (see <http://bugs.python.org/issue9033> for an example of why this is problematic).
