How do I install a non-outdated D compiler on Linux? (not in userspace-container)

[solidstate1991 via Digitalmars-d-learn]

I **need** to link against various system libraries, and 
otherwise some tools won't be able to access the D compiler 
unless I start them from a command line after an initialization 
script.

I'm using Linux Mint, it's much more stable than Ubuntu (which 
started to completely collapse on me for just looking the wrong 
way at it), but unfortunately some packages are outdated, 
especially the D compilers.
