Failed to start on RS212: not found

I installed VirtualHere USB Sharing on my Synology NAS (RS212) and so far everything went fine. However it can not start:

Tue Feb 4 22:44:10 CET 2014 Starting VirtualHere…
/volume1/@appstore/VirtualHere USB Sharing/vhusb: error while loading shard libraries: cannot open shared object file: No such file or directory
Tue Feb 4 22:44:10 CET 2014 Failed to start

What can I do? Is there any package that includes The core and common library is located in /lib/.

Thanks for your help.
