clone fails on mac osx 10.6

edit

Hello, I'm running OS X 10.6.8 and using a fresh untar of Sage 5.8 for 10.6, Intel, the non-app version.

"sage -clone" fails like this:

$ ./sage -clone pdiff
Now cloning the current Sage library branch...
hg clone  sage sage-pdiff 
updating to branch default
abort: data/sage/rings/power_series_ring.py.i@8c895bf765d1: no match found!
Error cloning

real    0m51.704s
user    0m6.099s
sys 0m2.200s

I found that power_series_ring.py exists in /Applications/sage/devel/sage/sage/rings but I do not know how to fix this issue as far as Mercurial is concerned. Can I rebuild the hg database? How else might I proceed to a fresh clone? Thanks!
