I realize your questions has been answered, but to answer two larger
questions in this whole thread ...
There's no general solution to the problem of, "I upgraded my OS/libraries
and nmh was linked with an older version of this library", except to
recompile. We try to make sure this process is easy and that varions
distributions come with a nmh package already available.
The "make uninstall" target is generated by Automake automatically; it
should remove everything installed by "make install". This is actually
checked by "make distcheck" and I make sure that nmh passes "make
distcheck" before a release, so there should be no problems with
