I found the --enable-low-memory option to LHAPDF, and it enabled me to get 
further. (Joachim Kopp also suggested I try it.)

After rebuilding LHAPDF and Genie, I now get:
... libGVHE.so does not exist ...
This looks like an inconsistency in the Genie makefile(s) or code. "configure 
--help" says that VHE is experimental. I added --enable-vhe-extension to my 
configure command and re-built Genie.

Note that "make distclean" has an infinite loop. (It's needed to do a second 
"make install".)

Now the "genie" command starts up without error messages.

I then realized that it is the "gevgen" program I am interested in. It also 
starts up without error messages, presenting the Genie banner, a bunch of INFO 
messages, and its Syntax.

So it looks like my build problems are over, assuming that --enable-low-memory 
won't prevent me from doing what I need to do.

Now I need to learn how to actually use it for something useful....

Thanks to all.
