Example ("hello world") program is not working

[merkys]

starta --help among other information gives a "hello world" example for --execute command line option:

andrius@amalas:~/debian-packages/starta$ starta --help
Compile and run an SLC program

<skipped for brevity>

Options:
  -c, --compile-only  Only compile a program, do not run it.
  -e, --execute '. 1' Execute a Starta program.
<skipped for brevity>

However, starta -e '. 1' does not work:

andrius@amalas:~/debian-packages/starta$ starta -e '. 1'
