(This is not a criticism as I have suggested using a virtual machine for gretl in the past myself.) For Windows users an alternative might be simply to use the zip distribution prepared by Allin (also on http://gretl.sourceforge.net/win32/), which doesn't require installation or anything and should "just work". See also some mailing list threads about using a USB stick to run gretl. On Linux I guess this is not so easy since the relevant libraries are not shipped with gretl, but always taken from the underlying system. (Of course one might run Wine and then use the Windows variant..., in theory.) So one remaining question: Does the MacOS package have everything that's needed and could be run from a USB pen/drive? (I'm asking for a friend, hehe.) thanks sven
