The modules have to be compiled before you can use them. Download the "textfile" with the extension .c into youre anope/src/modules folder. If you already have anope installed you can compile the modules with the command:
make modules
When this is finished install them with:
make install
Before you do this have a close look at the text in the modules. Some require you to set certain parameters before building them.. When the module is installed you have to add them to your services.conf file (pretty much at the end of the file is the module section). Hope that helps.
