PPR: PPR install bug fixed

[David Chappell]

Some of you have reported that when you build PPR from source code and 
run "make install" some of the programs are installed without necessary 
setuid bits set.  Mysteriously, if one runs "make install" in the build 
directory of any one of these programs, it is installed with the correct 
permissions.  This had me stumped for a long time.

I have finally traced the problem to the code which creates symbolic 
links in /usr/bin to programs such as ppr, ppop, and ppad.  It was 
running chown and chgrp on the symbolic link.  The intent was to change 
the ownership and group of the link, but the operation was actually 
action on the file to which the link points.  This had the side effect 
of clearing the setuid and setgid bits.

I have corrected the problem in both the 1.5X and the 2.XX branches and 
checked the fix into CVS.  Please try it out and give me feedback.  If 
all is well now, I will release a new minor version of PPR 1.5X with 
this and three other small bug fixes.
