Comment(by vbraun):
The problem is that the ctime of newly-created files over NFS is wrong:
{{{
vbr...@iras:~> rm -f test && touch test && stat test
File: `test'
Size: 0 Blocks: 0 IO Block: 8192 regular empty
file
Device: 14h/20d Inode: 11175765 Links: 1

}}}
There is a nfs bug related to nfs time stamps
https://bugzilla.kernel.org/show_bug.cgi?id=6127
which is likely the culprit here. That bug was fixed in 2.6.17 (iras runs
2.6.16).
A possible workaround would be to build sage in `/tmp`, which is a local
disk and where file creation times are correct.
