problem with vc-svn + tramp.

[George Nurser <agn@noc.soton.ac.uk>]

I am using emacs 22.0.50, running on a powerbook. When I use tramp to  
edit a file in a subversion directory by doing ssh onto a SUN  
workstation, it seems to automatically switch on the vc-svn mode. It  
then keeps failing, with the message

vc-do-command: Running svn...FAILED (status 127)

If I switch on 'Enter debugger on error' from the options menu and try  
to save a file I have modified
(/ssh:nilas:/data/jrd/occamd/AGN_MODEL/SUBVERSION/SOURCE/Makefile), I  
get a trace ending with:

Debugger entered--Lisp error: (error "Running svn...FAILED (status  
127)")
   signal(error ("Running svn...FAILED (status 127)"))
   error("Running %s...FAILED (%s)" "svn" "status 127")
   vc-do-command(t 0 "svn"  
"/ssh:nilas:/data/jrd/occamd/AGN_MODEL/SUBVERSION/SOURCE/Makefile"  
"status" "-v")
   apply(vc-do-command t 0 "svn"  
"/ssh:nilas:/data/jrd/occamd/AGN_MODEL/SUBVERSION/SOURCE/Makefile"  
("status" "-v"))
   vc-svn-command(t 0  
"/ssh:nilas:/data/jrd/occamd/AGN_MODEL/SUBVERSION/SOURCE/Makefile"  
"status" "-v")
    
vc-svn-registered("/ssh:nilas:/data/jrd/occamd/AGN_MODEL/SUBVERSION/ 
SOURCE/Makefile")
   apply(vc-svn-registered  
"/ssh:nilas:/data/jrd/occamd/AGN_MODEL/SUBVERSION/SOURCE/Makefile")


The important thing when i am working remotely is to be able to edit  
files; being able to perform the svn actions from emacs is not so  
crucial, so if anybody can tell me an easy way to switch off the vc-svn  
mode, that would be very helpful as a start.

I can edit the file OK if I do it through drag & drop & Samba. However,  
as I use fortran *.F and *.f files, & samba is case insesnitive, emacs   
eventually becomes confused. Hence I prefer tramp.

Incidentally, now does the vc-svn mode compare with the psvn.el  
available at http://www.xsteve.at/prg/vc_svn/ ? The svn commands from  
this do seem to work with the older version emacs (21.3.50 I think)  
that we have on the SUNs.

Any ideas appreciated. George Nurser.
