Hi AstonX,
DistroBuilder? Is that an application specific to Saluki? or did your download it from somewhere? If it was built into Saluki it probably won't work even from a Frugal Install: Saluki originally had its own repository and it's package manager was configured to use it. As was an application whose name I've forgotten. But this is what that application did: Saluki was the first Puppy to employ an 'adrv.sfs'. It came with one; but you could create your own. Instead of installing applications into a SaveFile, that 'builder' application would download all the applications you chose from the Saluki repository and repackage all of them into an adrv.sfs which Saluki would --like other parts of Puppies system-- copy into RAM on bootup.
That repository no longer exists. While it might be possible to add the current location of specific Saluki applications by re-configuring Saluki's Puppy Package Manager, that's not an easy task. Don't expect anyone else to volunteer to spend a great deal of time and effort.
Saluki was revolutionary; and it and its direct descendant, Carolina, were my favorites for a couple of years. But Saluki was published 10 years ago. That's about 200 "computer years". Both the computers operating systems run on and the applications (especially web and security) operating systems need have changed significantly.
Much of what jemimah pioneered with Saluki is now a Puppy standard. Adding to what bigpup has said about Frugal vs. Full perhaps this will help your understanding. You can mount the Saluki ISO by Left-Clicking it. In the window which opens you'll see files including adrv_lina_xx.sfs --the adrv I mentioned-- puppy_lina_xx.sfs and zdrv_lina_xx.sfs. The "sfs" endings stand for "squashed (compressed) file systems". A frugal 'install' works with squashed file-systems. It reads the content of a still 'squashed' file system and copy that content into Random Access Memory. A Frugal Puppy can do that with many SFSes, merging their content in RAM and thereafter running entirely in RAM; only writing to Storage occasionally and/OR only on user demand. If you Left-Click the adrv_lina_xx.sfs you'll mount/open it. In the window which opens you'll be able to view or file-browse to many folders and files. [Left-Click to Unmount/Close].
If you do a 'Full Install' what happens is that the installation program mounts both the ISO and the SFSes and copies the folders and files onto your Storage medium (Hard-drive). That system does not have Squashed files, nor any means to copy the contents of squash files into RAM.
All modern Puppies can make use of an adrv.sfs (and also a ydrv.sfs) to add entire suites of applications to your base system. And although the applications used differ from jemimah's 'builder', all modern Puppies are able to make such adrv.sfses or ydrv.sfses. These are two of the easiest: the Save2sfs module of the nicOS Utility Suite, viewtopic.php?p=12983#p12983 or PaDS, viewtopic.php?f=106&t=933
May I suggest a modern alternative which, like Saluki, uses the xfce window manager: DpupBuster xfce 32-bit. You'll find a link to it here, viewtopic.php?p=2208#p2208.
