I'm guessing that /opt/lam/intel/bin is not in your PATH. As the help
message states, LAM needs to have its executables in your PATH to
function properly -- can you check and see if it is?

If recon fails, lamboot is almost guaranteed to fail in the same way.

If you provide a command line argument to recon, it thinks that it is a
text hostfile. So it tried to read the lamboot executable as a text
file and got confused (hence the binary output in the error message).
