Works for me. Is your AMBERHOME environment variable set correctly?
Wei: sleap should probably print out the search path when emitting an
error message like the one above.

This is probably the same search path problem as above. And, I don't
see this behavior, so you might make sure you have the latest version of
sleap (AmberTools 1.2), if the AMBERHOME variable is not the problem.
