Cannot build Bison

[Tatsh]

main.log

Bison build failure is making it not possible to update my machine (I tried port upgrade -p outdated).

From the log:

I see nothing in that log which explains what went or goes wrong. I updated the port making it identical to the current mainstream port with just a bison-2 subport, can you try again?
