Helo,
By default, only "ctensr.mac" is copied to the installation directory. It can be loaded by
load("ctensr.mac"). This package is quite possible to use. At least I was able to reproduce all
examples in tensor.doc with it. However I would not say the same about itensor.lisp. It is left
in source dir after "make install" because it was not tested enough. To use it you can put
all files from tensor source dir in place where you want and
start maxima there. After this all commands to load packages will work.
It's pity but not all examples from tensor.doc are successfull for itensor.lisp. I guess it is due to the different versions of lisps between macsyma an maxima. I'm not sure about it
my knowledge of lisp is poor.
all the best, Valerij
