Are you running the latest version of rkhunter and did you try the
steps mentioned under "Problems running Rootkit Hunter?" on http://
rkhunter.sourceforge.net/ ? There are some issues regarding
prelinking and SELinux that can get you false positives.

Note that the binary is called MAKEDEV and not makedev. By default
grep is case-sensitive. You could use grep's -i switch (for case-
insensitive) or look for MAKEDEV instead.

Like 'man MAKEDEV' says: "MAKEDEV is a program that will create the
devices in /dev used to interface with drivers in the kernel." I
don't think a lot of MAKEDEV processes should be running during
normal operation, probably only during boot time?
