Upgrading PGP key to GPG key

[elf@florence.buici.com]

I've looked at the document that comes with debian-keyring.  It says
to run the command:

  gpg --load-extension rsa \
      --load-extension idea \
      --secret-keyring ~/.pgp/secring.pgp \
      --keyring ~/.pgp/pubring.pgp \
      --default-key 2EAE5D2D --sign-key FBCF8BFD

There are a couple of oddities.  First, it reports an error about
loading the rsa module.  I'd guess that only idea needs to be loaded.
This, though, it not expected since gpg reports that IDEA is already
supported  (gpg --version).  That isn't the real problem, though.

Now that I've signed my gpg key, what do I do to properly upgrade my
key in the database?  I'm concerned because when I check the key:

  elf@florence ~ > gpg --verbose --list-key singer
  pub  1024D/2EAE5D2D 1998-12-06 Marc Singer <elf@buici.com>
  sig        2EAE5D2D 2001-07-23  Marc Singer <elf@buici.com>
  sig        FBCF8BFD 2001-07-23  [User id not found]
  uid                            Marc Singer <elf@debian.org>
  sig        2EAE5D2D 2001-07-23  Marc Singer <elf@buici.com>
  sig        FBCF8BFD 2001-07-23  [User id not found]
  sub  1024g/D9531294 1998-12-06
  sig        2EAE5D2D 1998-12-06  Marc Singer <elf@buici.com>

There are missing userid, of course.  From the --edit-keys menu, I'm
told that:

  Command> check
  uid  Marc Singer <elf@debian.org>
  sig!       2EAE5D2D 2001-07-23   [self-signature]
  uid  Marc Singer <elf@buici.com>
  sig!       2EAE5D2D 2001-07-23   [self-signature]
  2 signatures not checked due to missing keys
  ^^^^^^^^^^^^^^^^^^^^^^^^

I hesitate to replace my pgp key until I know that it won't disrupt
the status of anything I've already uploaded.

TIA.
