Many thanks, Steve, for your effort on my behalf!  You reminded me that 
emacs provides a very nice way of viewing info pages.  I plan to use it 
more often.  It seems that $INFOPATH is alive and well.  I just figured 
out how I am supposed to use it.  It typically does not exist unless the 
user creates it because the info pages are made available from a central 
location (as you describe below).  So I would do something like this:

export INFOPATH=/home/mbmiller/local/info:

Note the trailing colon.  That is explained here:

"If you do not define INFOPATH, Info uses a default path defined when Info 
was built as the initial list of directories. If the value of INFOPATH 
ends with a colon (or semicolon on MS-DOS/MS-Windows), the initial list of 
directories is constructed by appending the build-time default to the 
value of INFOPATH."


So I think this works for me in my ~/.bashrc whether $INFOPATH existed 
previously or not:

if [ -d "$HOME/local/info" ]; then
     export INFOPATH=$HOME/local/info:$INFOPATH

If it did not exist, then I get this:

export INFOPATH=$HOME/local/info:

That is, I get the desired trailing colon described above.
