This error tells you that you don't have the Fortran kD tree built, which needs to be done by hand. If you are not interested in finding halos in parallel, nor two-point functions (like correlators or structure functions) this isn't a problem. This is just telling you that it won't work, so don't bother trying. If you want to make it work, you'll need to build the kD tree by hand:

This is telling you which color map is default. There are others available, I think, which the docs describe.

This warning comes from ipython, which is where the 'i' in 'iyt' comes from. ipython is a package that allows the interaction with the python command prompt to be more powerful. However, you are missing the GNU 'readline' library, which severely hampers ipython's power. This will only reduce the ease of use of the python command prompt, not your yt functionality. This is not a problem unless you want all the features of ipython.

Good luck!
