I don't know how apache works but it might be possible HOME is not set at all, what would gretl do in this case? Is there a way to pass config data to gretl on the command line? I could create an alias in that case. Or is there a global config that I could setup for gretl to use in these cases? In etc maybe? I can say now we are only interested in gretl's individual power, but it could change later. I do know we will never care about x11, it's a server environment, so it would still be a limited use configuration. Regardless, gretl is awesome, we do inventory and production forecasting with it and now I'm implementing a job times regression analysis, trend line, etc. Much better to use gretl than PHP that function out.
