I don't know about RH particularly, but if it is like Mandrake (most probably), installing from .rpm puts the files under /usr. On other side, installing with "configure && make && make instal" usually defaults to /usr/local. If you installed the old version from the distro media (.rpm) and the new version from source, you probably have the old version in /usr/bin and the new in /usr/local/bin. And while commands are looked for in /usr/bin before /usr/local/bin, the old version is found first. Try the commands with full path:
and if the 2nd runs the new version, then you have the situation described above. If so, you can uninstall the old with 'rpm -e' (see: man rpm). After you removed the old version, the system will find the new. By the way, one advice: as a newbie, use rpms instead of sources (you can find such at http://rpm.pbone.net
, since rpm cannot uninstall or upgrade packages that are not installed by rpm. If you want to uninstall a package installed from source, then you have to cd to the source directory and type 'make uninstall' (after install keep sources or at least the Makefile). If you want to install from source not in /usr/local, see 'configure --help', particularly '--prefix*' options.
