Cannot get ltplus to run

[robert atnip]

I'm having trouble with ltplus.  The files "ltpgo & ltplus" were located in my 
/home/atterbury/grass/4.1/ltp/bin directory.  When I tried to type ltpgo I got   the error message "No such command '/usr/local/ltp/bin/ltplus'".  I copied the 
"ltpgo & ltplus" files to /usr/local/ltp/bin directory, then when I typed 
ltpgo I got the message:


               setting internal variables:  paths.h
      from:  /usr/local/ltp

Could anyone please help.  Thanks
