'whereis portname' behaviour changed from 4.X to 5.X ?

[Rob]

Hi,

When I search a port with 'whereis', I get different results
on my 4.10 and 5.3 systems. For example

4.10 $ whereis lyx
/usr/ports/print/lyx /usr/ports/japanese/lyx

5.3 $ whereis lyx
/usr/ports/japanese/lyx


Why this difference?
On both systems /usr/ports/print/lyx exists.

Similar cases are there with other ports.
The result on 5.3 is rather confusing.

Rob.
