Has any had any luck using RCurl, JSONIO, or jsonlite in TERR?

Has any had any luck using RCurl, JSONIO, or jsonlite in TERR?  I can use them just fine in stat services and regular R, but when I switch to a TERR engine I get a very strange error,  For example, using the exact same library location I can load RCurl with R, but with TERR  I get:

> library(RCurl, lib.loc = "C:\\Users\\Daniel\\Documents\\R\\win-library\\3.0")

Loading required package: bitops 

Warning messages:1: In .parseNamespace(package, file.path(path, "NAMESPACE")) : package 'RCurl' exports 'curlOptions' multiple times2: In library.dynam(chname = chname, package = package, lib.loc... : 

Could not load foreign binary C:/Users/Daniel/Documents/R/win-library/3.0/RCurl/libs/x64/RCurl.dll: The specified module could not be found. Error during wrapup: attempt to set an attribute on NULLError in .loadNamespaceImpl(package, path, keep.source, partial) : 

error executing useDynLib for dynamic library 'RCurl' from package 'RCurl' loaded from C:/Users/Daniel/Documents/R/win-library/3.0 : Error in library.dynam(chname = chname, package = package, lib.loc = ... : Foreign binary RCurl could not be loaded

This happens whether I specify a library location or not, but it helps reduce at least on point of failure.

Thanks in advance!
