Hi: The utils, libs and drivers do need to be the same version number, but not necessarily the same letter. for example, you will probably want to use the latest release in the 0.5.11 tree for the driver. I would guess that there should also be lib and utils version 0.5.11 or something similar. What I'm saying is that 0.5 is a different beast to 0.4 and 0.9, and none of those will mix. So if you're using 0.5.9d or 0.5.11 or whatever, at the very least it needs to be version 0.5.x of the libs and utils. I'd get the latest of each in the 0.5.x range. Geoff.
