If so, what would be best practice to install 0.6-13? I could pin the version, but I worry I will forget about it when future versions come out.

Thanks for the email.  lavaan on Cran uses a dash, while the package 
built for Ubuntu via Debian uses a dot.  I will correct that in the next 
24 hours.  These small differences slip through sometimes.

Again, thanks for pointing that out.
