Getting latest LDC on ARM itself

[Cecil Ward]

On a Raspberry pi, ARM 32-bit, not 64-bit o/s unfortunately, 
running Ubuntu, I'm trying to get hold of the latest LDC to run 
it on ARM itself (ie not cross-compiling from an x86 dev system 
to an ARM target, but ARM on ARM).

I did a
    curl -fsS https://dlang.org/install.sh | bash -s ldc
but from the script, I get
     "Unsupported Arch armv7l"

* I can apt-get some version of LDC, but I don't know how out of 
date that package might be?
