Hi Sam,

it looks like you are running from within the yt-hg/yt/frontends/ramses directory.  Could you try running from a directory outside of the yt install tree (yt-hg)?  I think it is just getting confused by importing modules which are also in the directory.  Let us know if that fixes it.

I've recently installed YT and I'm getting an error in _ramses_reader.so when I start up YT; error message below. It's missing symbol _ZNSt8ios_base4InitD1Ev; Googling appears to suggest that it's related to Scipy. Am I missing something in the install? Let me know if you need any more information to unpick this one.
