This seems to be something more general than library paths. Even when
I get RCall working, it seems that R can't see the changes to
environmental variables made by Julia, i.e.
ENV["FOO"] = "bar"
rprint("Sys.getenv('FOO')")
doesn't work correctly (it returns a blank string, whereas on OS X it
returns "bar"). On the other hand, it does work the other way, i.e.
rprint("Sys.setenv(FOO='baz')")
ENV["FOO"]
gives the desired result. Is there anyway if I can tell if the problem
is on the Julia or the R end?
