working with and installing multiple versions of dmd and D's std-library on linux/ubuntu

[David via Digitalmars-d-learn]

Hi

I am wondering what a good strategy would be to install and work 
with multiple versions of DMD and the associated standard library 
on Linux/Ubuntu? The background is that for some features and 
libraries I need another compiler/std-lib version than for 
others. So having the opportunity to choose the compiler and the 
associated std-lib manually would be nice.
