The LED module is only a single terminal device.

Which explains that error message.
In general, you can query a device's pin names by:
gpsim> symbol D1.
D1 = Leds::Led
D1.in = stimulus attached to An1
Vth=5V Zth=1e+08 ohms Cth=0F nodeVoltage= 2.65V
Driving=0 drivingState=0 drivenState=1 bitState=Z
D1.xpos = 264.0000000000000
D1.ypos = 276.0000000000000
The ending '.' is like a wild card expansion character. All symbols in teh
symbol table beginning with D1 will get displayed. And as you may see, the
diode D1 has only one pin named 'in'.
Here's an .stc file that has the correct connections and places the diodes
in reasonable locations:
