Well, you really don't want to set DYLD_LIBRARY_PATH since it breaks dependencies, but that's another topic. However, the error tells you that you don't have it on the path, otherwise you wouldn't get "image not found". Either way, as I said, what you really want is to fix the id in the iomp library so you don't get into the path troubles in the first place. Another way to go about it is to put the Intel dependencies into $R_HOME/lib - I wouldn't do that for development but that's a good option if you want to distribute the build to other machines.

Cheers,
Simon

I don't think you should put them in manually. The actual error comes from missing libguide link flags, but they may be implicit if you fix the other problem.
