rsem tool installation from tool shed

I run a local Galaxy 19.05 on Ubuntu 18.04 LTS server. Tried to install RSEM tool, revision no. 14267d364365, owner jjohnson, from Everything goes OK, except there is an unresolved dependency. When I look at Tool Manager, it looks like the missing piece is the tool itself!

Does anyone knows what is going on? Is there any way to contact jjohnson the author directly?

Thanks a lot for any light shed (no pun… :wink: :innocent:)
