'comp' broke after fedora upgrade 29->30 | need help w/ Makefile targets

[nmh]

Hello:

After upgrading from fedora 29 to fedora 30, I get

  $ command comp
  comp: error while loading shared libraries: libreadline.so.7: cannot open 
shared object file: No such file or directory

I built nmh using the tar file and make

  $ mhmail -version
  mhmail -- nmh-1.7.1 built 2018-05-19 10:39:15 +0000 on epjdn.zq3q.org

but the build was done in fedora 29 or earlier.

What is best way to fix?  I assume I should back up 
/usr/local/nmh/etc
and then use make to remove the current install. How/which target?

Then I can build and reinstall.
