By modern standards, IDEA is not considered a promising cipher.  There
are some very good theoretical attacks against it.  Between the varying
patent expiration dates (2011 or so in some countries, IIRC) and the
thin safety margin, the GnuPG community has generally decided IDEA is
not a priority for inclusion.
