Ubuntu ruby ​​stones under rvm (unable to) install in the wrong place

Question

I run Ubuntu 10.04 and initially installed ruby ​​1.9.1 (from source). I just decided to try Ruby 1.9.2 and rails 3, and it seems like the right time to use rvm to work with multiple ruby ​​installations and gemsets.

rvm is installed and it seems to work, I installed ruby ​​1.9.2 in rvm and made it my default ruby. However, every time I try to install a gem under ruby ​​1.9.2, I see this error.

mark@Steve-Austins-Penguin:~$ gem install haml  
ERROR:  While executing gem ... (Errno::EACCES)  
Permission denied - /home/mark/.gem/specs

gem environment returns:
