 Is there any way of decide (within a script) if we run gretl_x11 or

Not really. On Linux you could probably do something clever with 
gretl's getenv() function and/or the $(...) mechanism for running 
shell commands and capturing the output, but even if possible it 
wouldn't be portable.
We could add a $gui accessor if there's demand for it.
