Somehow he knew about specifically that libcdt-4.dll was missing. I am just wondering how. We do know that libcdt-4.dll has been renamed. Unfortunately libgraph-5.dll has been renamed to libgraph.dll conflicting with the Bioconductor package graph, but that has been fixed by Patrick. It has always been essential that Rgraphviz is used with the same version it was build with. I have tried to do somediagnosis of this when loading Rgraphviz, but unfortunately (at least on windows), in this case (since it is not just a version conflict, but also a case of renamed dlls), it bangs out with an error before checks can be run. This might be fixable, but I will need a some way to test it on windows. Guess I need to look into getting a virtual machine. Have anyone tried running/building R under Fusion or Parallels on the Mac?
