Very interesting! I had been doing some housekeeping on some of my
older OS X build systems over the past few days and I've run into the
same problem. In particular, I am seeing this failure on an OS X 10.5.8
system (running in a Fusion VM) which I've used for years and from which
I have regularly cloned repos from hg.python.org. I spent some time
yesterday trying to isolate it. I came to the conclusion that it was
independent of the version of OpenSSL (identical failures occurred with
the system's ancient Apple 0.9.7 as well as a newly-build 1.0.1j) and
independent of the version of hg (at least with two data points, current
and a year-old version) and seemingly independent of the network
connection. I was not able to reproduce the failure on the host OS X
system (10.10) and I didn't have problems a few days earlier with
various other OS X releases (10.6.x through 10.9.x) also running in VMs
on the same host. I stumbled across a workaround for the problem as I
was experiencing it: adding --uncompressed to hg clone eliminated
failures. You can get more info on the hg failures by adding
--traceback and --debugger to the clone command. After spending way too
much time on the issue, I was not in the mood to spend more time
isolating the problem after finding a workaround but if others are also
seeing it, it might be worth doing. Sigh.
