www.linuxcnc.org/handbook/part1/software/rtlinux/prepatch20/rtl20.html#rtmodules

says concerning the kinds of messages you got.

-----start if quote-----
I got the following report on his recent install from "andrew a." <kn6za1-at-yahoo.com> 

Ok, I installed emc on red hat 6.1 again, this time I took better notes! 
My setup is 
red hat 6.1 
gnome workstation install 
rtlinux-2.2-prepatched.tar.gz file from site listed on linuxcnc.org 
june 7 emc
After following all directions on installing the rtlinux-2.2 kernel, I had two files that needed permissions changed before it would let me see the examples operate. Those files are, rmrtl and insrtl and they are both in the rtlinux-2.2 directory. 
[root-at-localhost rtlinux-2.2]# chmod -v a+rx insrtl rmrtl 
mode of insrtl changed to 0755 (rwxr-xr-x) 
mode of rmrtl changed to 0755 (rwxr-xr-x) 
[root-at-localhost rtlinux-2.2]#
Note - 2.0 - The examples are included in the rtlinux-2.0/rtl directory rather than as shown. 
-----end of handbook quote---

I haven't tried 2.3 yet but it sounds like the modules are not being
inserted into the kernel.  If you haven't already changed the permissions
you might try that.  It might also be that these files have been moved or
copied into another location in the new release and run from there rather
than from rtlinux-2.3.  You might try a system wide search for them and
see if they exist in more than one place.

When you get this figured out would you "patch" the handbook page for the
changes that are necessary.  Or send your notes and I can do it.

Thanks in advance.
