RVM was not able to detect your system type

My local OS is ubuntu 12.10, and I want to install rvm and ruby on remote server through capistrano. The remote server is SUSE Linux Enterprise Server 11

When I execute "cap rvm:install_ruby", it reports below error: 
RVM was not able to detect your system type and does not know how to load extra library paths for your system (if it's needed), read:

PS. 
1. rvm 1.20.13 (stable) was successfully install on remote server by executing "rvm:install_rvm"
2. If I set rvm_autolibs_flag to disable, ruby can be installed successfully.

How can I install ruby with rvm_autolibs_flag = enable?
