[Gretl-users] Unable to use X-12-ARIMA from Gretl

Hello I installed X-12-ARIMA with the debian package. The installation was succesfulll and I can run it from the terminal with ~$ x12a but I don't succed to use it from Gretl. - Writing arma 2 3; unemp --x-12-arima leads to an error message -The option "X-12-ARIMA" doesn't appear in the menu (it's stay in gray). I looked in the options and the path to X 12 Arima seems to be correctly x12a, which I could successfully use from the terminal. (The others options I could try, Web Navigator or PDF reading work) Should I do something more? Are you able to launch x-12-arima? Thanks a lot!
