in src/mhvtl/usr/Makefile, BINGROUP does not get defined, and must be fixed manually.

Also, mkvtl.service does not get created. You can run /etc/init.d/mhvtl start

Prior to start, you need to create, or after start, you need to edit these:
/etc/mhvtl/library_contents.10
/etc/mhvtl/library_contents.30

@xaminmo fixed, thanks!
