I am a complete beginner in terms of Linux and Porteus, so I apologize in advance for my stupid questions and for the wealth of questions...
I am not a complete beginner as I installed Linux Mint 15 Mate on my home laptop. But I didn't have to get my hands dirty, everything went just fine with all the programs I need.
But at work, my Win7 computer in my classroom is so restricted, that I can't do all the things I need to do. When I came across Puppy Precise, I thought all my problems were solved: I could boot my work computer from USB and have my own computer. But for some strange reasons, Puppy Precise does not work well on this computer (4GB RAM, dual core 1,8GHZ computer), then I came across Slax7 and now Porteus, which I can't really tell apart yet, I'm sorry.
But my problem is that I need 4 programs to do my work in class and in Puppy and Linux Mint they installed right away, but in Slax/Porteus, they seem impossible to get installed/working (I am still very confused about the difference between installing a package and a module, although I spent literally hours on end browsing through the forums and the tutorials.
So what I need are these four:
wine (to run my school/class administration software which only exists as .exe)
osmo 0.2.10 or 12
notecase 1.9.8 or the pro version if necessary
Kingsoft Office (at wps-community.org one can download a .rpm file, a .deb file and a tar.xz file, whatever this one is...) (I really am not able to get productive with LibreOffice Writer, and especially with LibreOffice Impress and I want to get rid of everything MS related, so no MSOffice in wine)
I went for Porteus 2.1 XFCE and at boot, it told me that as my USB is fat, I had to do a fresh boot. So I did.
I installed wine straight away via the Porteus Repo. The PPM told me everything went fine, I activated the module and so on, but it is as if nothing had happened. In the terminal "wine" is not know, but the PPM tells me the module is activated... Then I went to slax.org, downloaded their wine.sb module for Slax7 and then it worked ! in the terminal "wine" worked. BUT: I couldn't install my class-administration software, although in Slax7 this worked.

But what didn't work neither in Slax nor in Porteus are the other three:
I found Osmo via the PPM in the Debian Repo, converted it, activated but it doesn't work when clicked in the menu, and when I type 'osmo' in the terminal I get this error message: "osmo: error while loading shared libraries: libtar.so.0: cannot open shared object file: No such file or directory" So, there is a dependecy missing. I thought the whole point of a package manager is to resolve the dependencies, so what did I do wrong ?
(In fact, I do not really understand the Porteus Package Manager : what do I download ? Packages or Modules ? Is there a difference ? Is there a difference between slax7 .sb modules and Porteus .xzm modules ? )
Notecase 1.9.8 for example is available as a slack.tar.gz for slack 12.1 But I have tried everything with it, it just won't work...
same for Kingsoft Office.

So before I lose my mind, could a compassionate soul please explain how one goes about installing software in Porteus ? Especially software which has no specific module, but which exists as rpm or deb or tar.xz....
Thank you very much for your patience.
