Under Red Hat systems, /etc/profile is indeed the place to change it.

You'll note constructs such as this at the start of the file...

if ! echo $PATH | /bin/grep -q "/usr/X11R6/bin" ; then
    PATH="$PATH:/usr/X11R6/bin"
fi

These are done to add the path component only if it's not already there, to
avoid duplication, and to avoid simply clobbering the existing components in
the path.  Just mimic that construct for any additional directories you want
to add.

Note that this file (/etc/profile) will be used by any user (including root)
that has a Bourne shell (including bash) as their login shell.  You might
also want to do something similar for csh (and tcsh) users, by adding
something equivalent (with appropriate syntax for that shell) to the
/etc/csh.cshrc and/or /etc/csh.login files, if you have any users of those
shells.
