configure --prefix=/usr --sysconfdir=/etc && make && make install

Which means some time it got installed there, either by an rpm or
something else.

Do an actual rpm build and install from the rpm.  Or use the command I
listed above to get the configure directories correct (configure
defaults to /usr/local).  But it's generally best to have your files
tracked by rpm.  It makes upgrades and uninstalls work much more
smoothly.  And the rpmbuild program and the macros in the spec file
processing get all your directories correct for you too.  Assuming you
have an rpm based system that you are running from of course.  In that
case, it's fairly simple to do something like the following:

make dist
rpmbuild --rebuild <name_of_tarball>
rpm -Uvh ~/rpmbuild/RPMS/<arch>/<rpmlist>

You might need this in your ~/.rpmmacros file:

%_topdir %(echo $HOME)/rpmbuild
