When you say Serial, do you mean USB or RS232? I have not used gnoduino, but with had no problem compiling and uploading to Arduino Mega2560 over USB on Arch using avr-gccand avrdude. This is the avrdude settings I use: avrdude -c stk500v2 -p atmega2560 -b 115200 -P /dev/ttyACM0 -U flash:w:program-file.hex (You will need the root privileges for this). Attached the makefile if it helps you to get an idea.
