% cat <nbtfile> | nbted -p | nbted -r 
Error: Unable to read text file -                                                                                                                                                                                       
        caused by: No such file or directory (os error 2)                                                                                                                                                               
For help, run with --help or read the manpage.

I am using the latest version of rust via rustup with a freshly installed version of nbted via cargo.
