Yes, it's fallen a bit behind (the install).  It's b/c the VIPerl SDK includes the CLI commands, I think.  It would be nice if they bundled the VIPerl SDK modules (which are all pure-perl source files) as a CPAN module with appropriate dependencies.  There are some challenges since its using a deprecated SSL library.  You can do just the VIPerl SDK perl module install by hand, I've done it and it's not too hard, but I still have to drop LWP down a version or two to avoid some issues.
