After some research and testing, I have some conclusions. Here is my setup:
Redhat 9
CS 1.6 Dedicated (steam)
Realbot v1.0
No other plugins (yet)

This works. Just follow the directions on the installation page. You also need to add a symlink like this:
cd hlds_l/cstrike/dlls
ln -s realbot_i486.so realbot_i386.so

I think this has something to do with the most recent Steam update.

Some behavior that's weird:
If I copy and paste the following into the console, it doesnt add all the users:
rbds csversion_1
rbds addbot_1_5_5_b1ug0d-TDL
rbds addbot_1_8_5_Mr_President
rbds addbot_1_4_5_foobar
rbds addbot_2_6_5_I_love_CS
rbds addbot_2_7_5_n30
rbds addbot 2_4_5_pane-TDL

I have to add the users slowly one at a time.

If you type rbds csversion_1 for the first time, it changes the play to 1.6. If you type the exact command again, it switches it to 1.5. I don't think this is the intended behavior. You should have to explicitly type rbds csversion_0 to switch it to 1.5.

That is my $.02. Now that I have gotten this far, I am going to attempt to get my other mods running.


ALSO,

I tried the WIP version. I am confused on this. Is this a metamod plugin? If so, I couldn't get it to work.
