I have resolved this now. The problem was the VM primitive ioLoadModule() not being able to find libc. It has some heuristics for where to look but they don't work on NixOS. I added the relevant folder into $LD_LIBRARY_PATH in my wrapper script and now it is happy. There will be a lot of this in my future... finding hard-coded paths for things like shared libraries and un-hard-coding them. I am not sure what to do in cases where the paths are in Smalltalk code inside an image, that's harder to patch than the VM sources or ELF headers etc.
