"ide" global variable nil in "install.lua"

I got "dgate -v" to run on one of our openSUSE 13.1 servers, but I'm having some difficulty running the "install.lua" file from ZeroBrane. Here's the result when I load the file and do Project->Run (with zbstudio started as root)

Program 'lua' started in '/opt/zbstudio/myprograms' (pid: 3276).
/opt/zbstudio/bin/linux/x64/lua: ...s/dicom/server/conquestlinux/ZeroBraneStudio/install.lua:38: attempt to index global 'ide' (a nil value)
stack traceback:
	...s/dicom/server/conquestlinux/ZeroBraneStudio/install.lua:38: in main chunk
	[C]: at 0x00404f08
Program completed in 0.06 seconds (pid: 3276).

I've looked through the code and can't find anywhere that the ide variable is actually set. Did I miss a step? I'm guessing that ide should be internal to ZeroBrane, but it's not providing it (setting a Watch on the ide variable indicates that it is always nil).
