0140u2... I had to study the change log to recognize that SDL-ttf is needed now. After installing these packages, compilation works again.
Also, the new uifont-feature works great.
Although, I spotted some kind of strange behaviour: After starting mame and entering GUI, the line where you can enter the game title isn't set to random by default anymore. The word 'empty' is written instead and you'll have to delete it or just press Esc to return to random mode (shouldn't Esc quit mame?)
Another one: When leaving mame it often ends up with a black screen and pressing Esc once again finally quits the program and switches back to OS.
