First thank you for the release of Porteus 5.0

On previous versions, I was able to install and create modules from Slackware repositories.
I had a problem with my laptop, and I was able to fix it thanks to a wonderful program called testdisk. I plan to make a USB bootable with Porteus from a tailored one created in a Virtualbox virtual machine. But I need to install several programs, some of the ones described here, including testdisk:

Searching in this forum I got random blank pages with error 500 from Porteus forum, sorry, I was not able to find information on the subject.
Is there a tutorial on how to install programs in Porteus?, the modules are great, but I miss some programs, thanks a lot.
Best regards
