With my setup I get this pretty often:
{{{
The Sage installation tree has moved
from /waste/cn/sage-5.6
to //waste/cn/sage-5.6
Updating various hardcoded paths...
}}}
Source of the confusion appears to be an extra symbolic link {{{/jehova ->
/}}} (that I need if I want to follow the link through an nfs share):
{{{
cn@jehova:/waste/cn> ll -d sage*
lrwxrwxrwx 1 cn users 25 Jan 26 13:19 sage -> /jehova/waste/cn/sage-5.6
drwxr-xr-x 8 cn users 4096 Jan 26 14:45 sage-5.6
cn@jehova:/waste/cn> ll -d /jehova
lrwxrwxrwx 1 root root 1 Jan 10 2009 /jehova -> /
}}}
The attached patch uses {{{os.path.samefile}}} for path comparison and
fixes this.
