gpg wants IDEA

Hello,
  I have an older gnuPG (v1.4.6) that is apparently mis-configured.
When signing a message, it fails with a note about what a bad idea
IDEA is, and quits. gpg is called from an email program to perform
security services. There is no command option to indicate a preferred
cipher.

- ----[ command ]----
gpg.exe --passphrase-fd 0 --batch --armor --no-tty --status-fd 2
- --local-user person at example.com --output output.pgp --clearsign
input.bod 2> splat.err
- ----[ end ]----

- ----[ error ]----
gpg: protection algorithm 1 (IDEA) is not supported
[GNUPG:] RSA_OR_IDEA
gpg: the IDEA cipher plugin is not present
gpg: please see http://www.gnupg.org/faq/why-not-idea.html [^] for
more information
gpg: skipped "person at example.com": unknown cipher algorithm
gpg: W:\APPS\PMMAIL\TESTACCTS\test1_00.act\outbox.fld\nge4mh01.bod:
clearsign failed: unknown cipher algorithm
- ----[ end ]----

Why would gpg feel compelled to use IDEA?
How do I convince gpg to forget about it?
