OCAML_TOPLEVEL_PATH="/home/jharvard/.opam/4.01.0/lib/toplevel"; export OCAML_TOPLEVEL_PATH;
MANPATH="/home/jharvard/.opam/4.01.0/man:"; export MANPATH; PATH="/home/jharvard/.opam/4.01.0/bin:/etc/log50.d:/etc/log50.d:/usr/lib/qt-3.3/bin:/etc/log50.d:/usr/libexec/lightdm:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/jharvard/.local/bin:/home/jharvard/bin"; export PATH;

And then it still says that the "utop" command is not found. The paths above are gibberish to me. Would anyone be able to look at what it returned to see if that indicates what the problem might be?
