Distribute System from non-Symbolics?

[John Sterling <sterling%cs.nyu.edu@RELAY.CS.NET>]

Hi.  We are unsuccessful at writing a distribution tape that includes
files stored on our Suns.  The Distribute System framework has no
difficulty generating the plan, but when it goes to write the files,
any file on the Sun results in an error as follows:

 Error: Can't find a length property for PROTEUS:BASICS;FOOBAR.LISP.NEWEST.  
 The file is probably an opaque link.

Have we overlooked something in the Host entry for the Sun?  Are
unix42 based files unacceptable for writing Distribution tapes?

Thanks for your help,
