cannot install XLD

[eljojo]

Hi,
I just tried to install XLD and brew-cask asked me to report an issue.

First, I tried running brew cask install xld and it got stuck at 100%, like this for about half an hour until i ctrl+d' it:

$ brew cask install xld
==> Downloading http://downloads.sourceforge.net/project/xld/xld-20141129.dmg
######################################################################## 100.0%
^C

then, I re-ran brew cask install xld and it failed with the following:

$ brew cask install xld
==> Downloading http://downloads.sourceforge.net/project/xld/xld-20141129.dmg
Already downloaded: /Library/Caches/Homebrew/xld-20141129.dmg
Error: no implicit conversion of nil into String

Sadly, I'm not really familiar with cask's nor brew's internals.

Your brew-cask is out of date. Run brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup, then try again.

Hi!

This is a duplicate of #7946.

A fix has been in release since v0.50.0. The following command should fix the issue:

$ brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup
