[julia-users] PyCall complaining about ambiguous method defs after recent clone of julia

[Stephen Pope]

Yesterday afternoon, I made a new clone of julia - (0.3.0-prerelease+888) 
commit 119ebc2. After that, PyCall has
been complaining about ambiguous method definitions:

julia> using PyCall
Warning: New definition

I tried removing and re-cloning PyCall (v0.3.1 is what I had before, and 
what I get now), but to no avail.

Any ideas?
