Not at the moment.
But if you will really need it, we can probably build the package for Linux too (it uses SWT, so we will need to package Linux SWT libs instead of Windows libs).
We are thinking about moving away from SWT for PTL Trader 2.0 and make it fully portable.
Anyway, it will still need the X session running (it is a GUI app), but IB Gateway/TWS needs it too.
