HTTPC.get on Windows 8.1 with Julia Studio 0.4.4

[peterquirk]

For my very first experiment with Julia, I'm trying to access a REST endpoint with this tiny piece of code:
using HTTPClient.HTTPC
using JSON
using Base.Test
statsUrl = "http://192.168.8.73:8888/api/v1/stats/storage"
println("About to access URL : $statsUrl")
r=HTTPC.get(statsUrl)
@test r.http_code == 200
println("Test 1 passed, http_code : " * string(r.http_code))

The program outputs:
About to access URL : http://192.168.8.73:8888/api/v1/stats/storage
LoadError("C:/Users/pquirk/Documents/julia/testHTTP.jl",8,ErrorException("error compiling get: error compiling setup_easy_handle: could not load module c:\users\pquirk\Documents\julia\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin\libcurl-4: The specified module could not be found.\r\n"))

I have installed HTTPClient, JSON, LibCurl, amongst other things. What do I have to do to configure my environment correctly?
