That should end up in scan.o, generated by the ylwrap script from scan.l. It doesn't appear to be a bison port version issue, or having bison and/or flex ports installed. 10.4 or 10.5?

[vinc17@…]

10.4 (I also have the bison port installed).

Issue confirmed on 10.4 with html-xml-utils 5.0 and 5.2 when the flex port is not installed. html-xml-utils 5.5, to which I just updated the port, also seems to fix this.
