Help adding IDEA within GnuPG 2.0.9

Hi group,
I am trying to include support for IDEA within GnuPG 2.0.9 running under 
Linux. I have downloaded the idea.c module via the link on this page:, have compiled it and have 
added the 
        load-extension <path-to-idea>/idea
statement to my conf file in ~/.gnupg/gpg.conf

But it does not seem to load IDEA support anyway. I have placed the idea 
module in the ~/.gnupg/ folder - could that be the problem ? 
I have verified on another server - with GnuPG 1.4.10 installed - that 
here the IDEA support actually gets added with this setup.

The "gpg --load-extension <path-to-idea>/idea -v --version" command within 
GnuPG 2.0.9 yields the following:

batch at psdkxd02:~/.gnupg> gpg --load-extension 
/usr/local/ps/batch/.gnupg/idea -v --version
gpg (GnuPG) 2.0.9
