Sage 4.5.3 to 4.6 upgrade fails when distribute is installed

[Koen van de Sande]

Hello,

I have a Sage 4.5.3 installed, with the Distribute (a kind of improved
setuptools?) package installed in there. Now, when I upgrade, Sage
insists on reinstalling setuptools 0.6c9, which is incompatible with
Distribute. The latest release 0.6c11 has no such issues with external
packages: http://pypi.python.org/pypi/setuptools
IIRC this update specifically fixes this issue. However, I can install
the newer setuptools all I want, Sage keeps reinstalling the older
version. Is there anyway to block the installation of a specific
package?

sage: An error occurred while installing setuptools-0.6c9.p0
Please email sage-devel http://groups.google.com/group/sage-devel
explaining the problem and send the relevant part of
of /home/ksande/bin/sage-4.5.3/install.log. Describe your computer,
operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/home/ksande/bin/sage-4.5.3/spkg/build/setuptools-0.6c9.p0 and type
'make check' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
(cd '/home/ksande/bin/sage-4.5.3/spkg/build/setuptools-0.6c9.p0' && '/
home/ksande/bin/sage-4.5.3/sage' -sh)
When you are done debugging, you can type "exit" to leave the
subshell.
