That is not precisely correct. A source kit for GnuPG can be found in e.g.
while the IDEA patch is found in e.g.
It would be correct to say that Gentoo does not distribute GnuPG
binaries, with or without IDEA. The package management system
(portage) gathers tarballs, patches, etc., constructs a source tree,
and compiles it on the target system.

The "instructions", to be clear, are the ebuild file that portage uses
to automagically build the software for you.
I can state that I have GnuPG built by portage on my Gentoo systems,
and it does not include IDEA.

A quick look at the 2.0.7 ebuild suggests that portage will apply the
IDEA patch but not enable IDEA. But I'm nothing like a portage
expert, so don't give my analysis of ebuilds too much weight.

Typically when a software vendor says that a product is "intuitive" he
means the exact opposite.
