Software Serial clash with Margay

[ericbarefoot]

With the following MWE:

#include "Margay.h"
#include "Matbotix.h"

void setup() {}
void loop() {}

I get the following compiler error:

libraries/SoftwareSerial/SoftwareSerial.cpp.o (symbol from plugin): In function `SoftwareSerial::read()':
(.text+0x0): multiple definition of `__vector_4'
libraries/Margay_Library/Margay.cpp.o (symbol from plugin):(.text+0x0): first defined here
collect2: error: ld returned 1 exit status

A quick internet suggests that this means SoftwareSerial and some part of Margay are fighting for the same timer or pin-change interrupt. I do not know enough at the moment to diagnose which resource the two libraries are trying to fight over, so I am dropping this here in case someone else will be able to identify it faster.

Could it be possible to use Serial to communicate with the sensor instead of SoftwareSerial?
