'make index' failure

[Francisco Azinsan]

Hi, 

I performed an 'rm -rf /usr/ports' followed by a cvsup for ports-all from
cvsup4.freebsd.org, and attemped a 'make index'. It failed with the
following error: 

  aerie# make index
  Generating INDEX - please wait..maildrop-1.6.3: "/usr/ports/databases/gdb"
  non-existent -- dependency list incomplete
  ===> mail/maildrop failed
  *** Error code 1

  Before reporting this error, verify that you are running a supported
  version of FreeBSD (see http://www.FreeBSD.org/ports/) and that you
  have a complete and up-to-date ports collection (INDEX builds are
  not supported with partial or out-of-date ports collections).  If
  so, then report the failure to ports at FreeBSD.org together with
  relevant details of your ports configuration (including FreeBSD
  version, environment and /etc/make.conf settings).

Please can you advise me if there is something I need to fix on my end, or
if it's a problem with the CVS versions.

Thanks.
