Ugh, apologies for the direct reply to Uwe Brauer instead of the list.

Yes, as long as your key requires the use of IDEA-encryption,
everybody who's trying to encrypt to you has to use an IDEA-enabled
client. In the case og gnupg that means that one has to compile in
idea.c or use idea.dll (on windows).
