If i want to install older version of a program that require older versions of dependencies and i don't want to downgrade my system wide installed dependencies is it possible to install the program with its dependencies in somehow isolated environment and make the program use this dependencies instead of the system wide installed dependencies?
I don't mean VM but something that will work similar to how portableapps.com apps work for Windows. They have all dependencies in the portable app folder, like Pidgin for example.

Sounds like a recipe for dependency hell if you do this for more than a couple of programs.
Anyway it says
Quote:
PortableApps.com Updater - Your Apps Are Up To Date - With PortableApps.com, you don't need to worry about making sure your software is up to date. Just click a button and the updates are downloaded and installed without messing up your settings and saved files.
You just want any Linux live distro that supports persistence from USB such as Ubuntu etc.
Distribution: Currently: OpenMandriva. Previously: openSUSE, PCLinuxOS, CentOS, among others over the years.

What exactly do you mean by a "isolated environment"?
As the only thing that I think of by that, is what JeremyBoden, has already suggested (being a VM).

Would definitely agree.
As I don't think we can give you a proper answer based on what you have asked so far, so maybe provide us with a more specific question.

Reason: "definitely" instend of "defiantly" + added "more"
A chroot is a partially isolated environment. If you compile from source you can have all the deps in $HOME/ and do a lot of funkly $PATH and $LD_* stuff to run that version with libs from the $HOME. But it's a lot simpler to use a vm / docker / chroot. Or to have a dedicated cheap device like a raspberry pi configured for the older software needs.

debootstrap installs a minimal system intended to be used as a chroot. I use it to do full installs. But you have to install a kernel before booting it, plus set a root password, and other admin steps normally done by an installer. It could be done with debootstrap. Depending on how much effort you want to put into the process.
