[Pgbuildfarm-members] misterious error "491 Unknown" from pgstatus.pl

Hi there,

I've got a problem with my (new) build farm member tucuxi (a dolphin, of all animals!),
replacing guppy.

It's running Open BSD 4.1 / i386 with the build farm client 2.18.
I can get it to the point of building everything:

-bash-3.2$ ./run_build.pl --test
[17:43:20] checking out source ...
[17:43:41] checking if build run needed ...

[18:11:01] OK
Branch: HEAD
All stages succeeded

But when trying to submit, pgstatus.pl returns a misterious error "491 Unknown":

-bash-3.2$ ./run_build.pl --force
Query for: stage=OK&animal=tucuxi&ts=1178387020
Target: http://www.pgbuildfarm.org/cgi-bin/pgstatus.pl/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

(xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx is mine)
What might be happening here?

Bye,
Chris.
