Per bento logs, this is broken on 5.x. Rather than marking it so only
for 5.x, mark it as generally broken; the latest distfile in the 1.x
series was in 1996 and this isn't even it (this one is from 1994). The
bash2 releases began in 1996.
Unless there is some absolute need to maintain this port for backwards
compatibility, it should probably just be deleted.
