It works when I do it.

aleph% more .Rprofile
.First<-function(){
  print(".First is being run")
  dyn.load("~/Rarchive/libloc/survival5/libs/survival5.so")
  print(is.loaded(symbol.C("coxdetail")))
}
aleph% R
...

[1] ".First is being run"
[1] TRUE

What are the symptoms: do you get an error message? How do you tell it
wasn't loaded? Is .First() being run?
