error running 4gl runtime via remsh

hi, I have a script that loads data from an hp-ux 10.01 box running ods 7.13UC3 to a sun 5.5.1 box running ods 7.12UC4, and after inserting the rows in the table, it executes the 4ge file. the dbload portion of the script works fine, but when it comes to running the 4ge file, i get the following error: Please install an INFORMIX-4GL Run Time Facility and run this program again. If i run the 4ge on the sun box, either thru command line or in a script, it runs beautifully, but if i do remsh servername -n /dirname/prog.4ge i got the above message. I have tried putting the 4ge in a script and have the remsh executes the script, or pipe it through at, but i still get the same error message. anyone has any ideas? thanks in advance, hk
