No matching function for call to 'HardwareSerial::begin(int, UARTClass::UARTModes)'

I'm trying to compile the IBusBM library for the Arduino Due, but I'm getting the following error:

WARNING: library IBusBM claims to run on avr, esp32, stm32, mbed architecture(s) and may be incompatible with your current board which runs on sam architecture(s).

Error compiling for board Arduino Due (Native USB Port).

I know that the library claims to be incompatible, but I figured I'd try to compile it to figure out why it is incompatible.
The library compiles without problems for just about any other board I've tried.
Is there something I can fix on the library side, or is this really a problem in the BSP?

Looks like a duplicate of #31 actually.
