Trying to run standalone (headless) on Linux (Ubuntu) - failed at first hurdle

[Ben Rubinstein]

Thanks Panos.

I'd just got part of the way there from your comment on this 
https://quality.livecode.com/show_bug.cgi?id=23163 report.

(I'm a complete Linux noob.)

So now I know about 'ldd' I was able to execute:
> # ldd CB304 
> 	linux-vdso.so.1 (0x00007ffed1b36000)

I was able to use apt to install "expat" and "fontconfig", but it couldn't 
find "freetype".

Nonetheless I thought I'd try my app again, hoping at least that the error 
have moved on. But alas:

> # ./CB304 -ui
> ./CB304: error while loading shared libraries: libexpat.so.1: cannot open shared object file: No such file or directory


Also - can you confirm whether LC standalones (built from 9.6.6) should be 
able to run on Ubuntu 18? Or is Ubuntu 16 the limit?

Many thanks,

Ben
