 When playing with bash-completion (great job, BTW!) I noticed an error
 when using "vncviewer":
 {{{
 vncviewer readlink: illegal option -- f
 usage: readlink [-n] [file ...]
 }}}

 It turns out that, big surprise, bash-completion requires the GNU version
 of the readlink command, not the BSD. Rather than mess around with command
 line options (it is possible to simply remove the unsupported "-f" option
 and hope for the best!) I decided to patch in a dependency to "greadlink"
 from coreutils.

 Works like a charm, now.
