This is caused by the colon that is used in the reference syntax being included in the filename of the .hex file.

Which board have you selected? I see the bug but I would like to reproduce it myself, instead of blindly fixing it

That particular error message came from a work in progress board but Adafruit Metro will do it:

Fixed. Fix will be available with next hourly build http://www.arduino.cc/en/Main/Software#hourly
