Which version of anope (1.6.x, 1.7.x, 1.8.x), and which medium (BSD, Linux, Windows, other) are you trying to install this module for?
The published module is for *nix, and for 1.7.x series up to 1.7.21. There is apparently a patch for 1.7.22, but it will not work with 1.7.23, .24, or with 1.8.0-rc1.
This is all noted in the final pages of
this thread.
