Many many things can change in five years.
So, yes, verify with a more recent version as 2.76.

My first thought would be "file versus directory". But man page from git
says:

       --dhcp-hostsfile=<path>
              Read DHCP host information from the specified  file.  If  a
              directory  is  given,  then read all the files contained in
              that directory. 

In other words a directory path is valid for --dhcp-hostsFILE

Could it be that the bad option is caused by bad content in the file(s).
