tclrivet parse error (wrong # args: should be "parse")

[Alexey Noskov]

Hello,I get an error when try to parse .rvt files from tclsh or wish (outside 
of apache):  % package require tclrivet
0.1
% parse "/home/local/htdocs/index.rvt"
wrong # args: should be "parse"
Is there any possibility to fix it? Thank you for your answers
