[mythtv-users] IR transmitter

[pete]

Hi all,

I'm using a universal O-F-A remote following Jarod's guide for use with
the Hauppauge pvr-250 receiver. That part works great. 
The whole mythtv install is from Jarod's guide also.

Now I need to change channels on my dish receiver.

I'm having trouble setting up an IR transmitter following the how-to
from a link that was sent to me. I don't remember who sent it.
The link is;

Everything goes well till I get to

$ /sbin/update-modules
bash: /sbin/update-modules: No such file or directory

If I try 
$ /sbin/depmod -a 
I get 
depmod: *** Unresolved symbols in
/lib/modules/2.4.22-1.2188.nptl_48.rhfc1.at/misc/ledxmit_dev.o
depmod: *** Unresolved symbols in
/lib/modules/2.4.22-1.2188.nptl_48.rhfc1.at/misc/ledxmit_serial.o

If I then try
$ /sbin/modprobe ledxmit_serial
I get pages of Unresolved symbols.

Is there a better/newer/easier method of doing this?

TIA,
--Pete
