[ixpmanager] IRRDB back-end not working

[Kyle Spencer]

I have followed the instructions here:
https://docs.ixpmanager.org/features/irrdb/

When I reach the "Usage" section and run the following command:

php artisan irrdb:update-prefix-db

I get a screen full of this:

The PHP Data Structure Ds\Set extension is not loaded/available.
Falling back to polyfill which, in extreme cases, can take ~3 hours.
Install the php-ds extension!

I have tried to manually execute the command as outlined by the
documentation and that does not work properly either:

bgpq3 -h whois.afrinic.net -S AFRINIC -l pl -j AS29032

However, getting rid of the "-h <HOST>" and "-S <SOURCE>" command line
options does work:

bgpq3 -j -l pl AS29032

Any idea what's going wrong in the background? Where can I modify the
command it's using?
