Read the source. Below the legal stuff it says:

/* How to compile:
 *
       gcc -Wall -O2 -shared -fPIC -o idea idea.c
 */

and place the resulting executables in the gnupg dir. Then add to your
options file:

load-extension rsa
load-extension idea

and you're done.

Sorry, details like these bothered me never enough to find that info.
I believe that some institute think they can patent IDEA (RSA is only
patented in the USA anyway) but I doubt that patent is valid in my
country (The Netherlands) anyway.
