perl: can't run berp/berp on linux

[ehuelsmann]

Summary

I'm having a look at updating the Perl implementation. I'm trying to run the first step: generating the parser using Berp, however, it fails.

Expected Behavior

After cloning the cucumber/cucumber repository and changing the directory to cucumber/gherkin/perl, I expect the command berp/berp.exe -t gherkin-perl.razor -g gherkin.berp -o p.pm to complete successfully.

Current Behavior

The command fails with the following output:

$ berp/berp.exe -t gherkin-perl.razor -g gherkin.berp -o p.pm

Context & Motivation

I'm unable to determine whether or not I'm able to provide an update to the Perl implementation.

After:

$ sudo aptitude install libmono-microsoft-csharp4.0-cil

I now get a different error:

The big question is: Which file????

[ehuelsmann]

Ok. So, after

$ sudo aptitude install mono-mc

I'm now able to generate the parser. Would have been good to provide the list of prerequisites. Consider this a request to add better documentation for those who want to start contributing. This is currently quite discouraging.

[ehuelsmann]

@aslakhellesoy in which file should I add the documentation about the berp dependencies?

[ehuelsmann]

@aslakhellesoy, ping?
