only syncing to sync-cache - * sh: ncftpput: not found

[gosuto-inzasheru]

I was able to install this project on a remote server and set up my repo with a WebHook URL to my post-commit.php file. Configuring the config file is, as far as I can tell, successful as well.

But when using the test hook function on my repo admin panel I can only see a successful sync to /sync-cache/. When checking the log I come across two problems:

SYNC CONFIG FOUND

------------------------------ Config check
Cache dir: [...]/github-webhook/sync-cache/[my-repo]
Hosts to sync:
==========
----- prod
Task:
ncftpput -F -D -R -u [user] -p [password] 127.0.0.1 $srv_path/ [...]/htdocs/www/github-webhook/sync-cache/[my-repo]//* 2>&1

First problem I see here is that $srv_path is parsed as a string not a variable. I can't find where it is supposed to be defined either. Isn't this suppose to be $path (or $path$repo_path)? What about the trailing //* in the $from directory?

CLONE and UPLOAD then go well except for the last line before the end:

* sh: ncftpput: not found

** SYNC FINISHED **

Is this a problem with my hosting (missing module/no shell access) or related to the first problem? And if it is indeed a problem with my hosting, what are the alternatives for this line?
