What are duplicate INDEX entries and why do I have them?

[Jens Schweikhardt]

Dear ports guru,

out of curiosity, with a ports tree cvsup'ed right now and checked out
(and for the last months as well) I see

portsdb -Uu
Updating the ports index ... Generating INDEX.tmp - please wait..
Warning: Duplicate INDEX entry: freeciv-gtk2-1.14.1
Warning: Duplicate INDEX entry: mod_jk2-apache2-2.0.2
Warning: Duplicate INDEX entry: mod_rpaf-ap2-0.5
Warning: Duplicate INDEX entry: fvwm-imlib-2.4.18
 Done.

Does anyone else have duplicate INDEX entries? Is something stale in
my ports tree?

Regards,

	Jens
