The approach I'd use:

Run rterm or rgui in the same way you were running R. Print 
sessionInfo() and Sys.getenv() and look for strangeness.  (In the 
latter, look at the variables whose names start R_.  See if they're 
different than when you successfully run R gui in the usual way.) If
the interactive run works, then you could put those two diagnostics into 
your script, and try again.
