Really?  Which "other people"?  Link?  

My Google-fu only turned up one other instance of this error, and the
error was reportedly resolved by installing the dependencies.

Jason,

Please don't hijack the thread.  People who use threaded mail readers
will have difficulty following or finding your question.

Assuming you used the script from the prior thread, I had no problem
running that code on multiple machines and R versions.  

The error itself suggests that something is masking objects like
optimize.portfolio in your .GlobalEnv, but without more information
there's nothing to diagnose.

Please try to follow the posting guide:

At a minimum, please provide the output of 

sessionInfo()
