     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.8.0
 Keywords:               |       Port:  mcfly
-------------------------+--------------------
 I recently upgraded mcfly to 0.7.1, and now after every shell prompt I get
 a message saying:
 {{{
 error: The argument '--append-to-histfile <HISTFILE>' requires a value but
 none was supplied

 For more information try '--help'
 }}}
 The mcfly port already contains the following notes:
 {{{
 $ port notes mcfly
 --->  mcfly has the following notes:
   If you are running bash as your shell, add:
       if [[ -r "/opt/local/share/mcfly/mcfly.bash" ]]; then
           source "/opt/local/share/mcfly/mcfly.bash"
       fi

   ...to your ~/.bashrc, then run:
       $ . ~/.bashrc

   If you are running zsh as your shell, add:
       if [[ -r "/opt/local/share/mcfly/mcfly.zsh" ]]; then
           source "/opt/local/share/mcfly/mcfly.zsh"
       fi

   ...to your .zshrc, then run:
       $ . ~/.zshrc

   If you are running fish as your shell, add:
       if [[ -r "/opt/local/share/mcfly/mcfly.fish" ]]; then
           source "/opt/local/share/mcfly/mcfly.fish"
       fi

   ...to your ~/.config/fish/config.fish, then run:
       $ source ~/.config/fish/config.fish
 }}}
 It seems as though these notes about shell integration might need to be
 updated? (I'm using bash for my shell, btw)
