[SAL-HELP] Path explorer

[Rimvydas Ruksenas]

Hello,

I have a problem with sal-path-explorer. I tried it
with several specifications. In all cases it right
away printed the following message:

   Error: Unbound variable

I get the same error message even when running it
with the example suggested by sal --help:

   sal-path-explorer peterson system

Could someone help?

Thanks,
Rimvydas
