[yt-dev] TipsyDataset Will Not Load, and Requires Parameter File

[Cameron Hummels]

I have tested this.  I was running from within the agora dataset directory,
which shouldn't make a different.  I went to its parent directory and
included the full path, but it still fails.  I've tried this on another
system with the tip, and it works OK, so I'm trying to figure out what went
awry on this system.  Hmm...
