Thanks lithos, i will follow the tutorial now.

It is not at all uncommon to have multiple versions of a language-environment on the same machine. You simply have to know how to keep them apart.

You need to put the proper executable ahead of the others in the search-path, and you need to adjust any library-location settings that the executable might refer to. (And you might well need to rebuild that library in a new location under the new version of the language, since many packages conceal quite a bit of complexity under their covers.)

The most common strategy (in Unix/Linux) is to make necessary environment-variable settings in a .bash_profile file for a particular user. It is often advantageous to have that script execute a common (probably home-grown) script that actually issues the right settings so that the latter can be reissued from a script or command-line.
