Yes, this is OK.  There is no _transforms.py

My guess is you are trying to run matplotlib from the build dir.  You
cannot do this, because python finds the matplotlib src dir named
matplotlib and tries to load that.  There is no _transforms module in
that dir, but there is in site-packages so you should be OK.  cd into
another directory, ie your home dir or the examples dir, and try from
there.

This problem bites a number of users.  Perhaps we should rename the
base matplotlib python dir in the src tree to something like
matplotlibpy.
