If I try to launch

bunzip2 < '/usr/local/rvm/archives/ruby-1.8.7-p334.tar.bz2' | tar xf --no-same-owner - -C /usr/local/rvm/tmp/rvm_src_6726

I get the same error.

But if I remove '--no-same-owner' the promlem dissapeared.

How can I fix the error?

It is bug in rvm, see latest commit https://github.com/wayneeseguin/rvm/commit/52018750763d5321b7b993e201c8589b98e090f9

rvm get head && rvm get stable && rvm install 1.9.3

Hmm... I install under no-root account and the problem disapeared.
