problem with libyaml

Hi all,

I am a total newbie in both ruby and rails development.

I have problem with libyaml (apparently).

I had rvm installed and did: rvm install 1.9.3. Installation of ruby was completed successfully however it complained about libyaml (below):

Fetching yaml-0.1.4.tar.gz to /Users/pouya314/.rvm/archives Extracting yaml-0.1.4.tar.gz to /Users/pouya314/.rvm/src Error running 'tar mzxf /Users/pouya314/.rvm/archives/ yaml-0.1.4.tar.gz -C /Users/pouya314/.rvm/src ', please read /Users/ pouya314/.rvm/log/yaml/extract.log Configuring yaml in /Users/pouya314/.rvm/src/yaml-0.1.4. Error running ' ./configure --prefix="/Users/pouya314/.rvm/usr" ', please read /Users/pouya314/.rvm/log/yaml/configure.log Compiling yaml in /Users/pouya314/.rvm/src/yaml-0.1.4. Error running 'make ', please read /Users/pouya314/.rvm/log/yaml/ make.log

I ignored the error at the time and went on to install rails but i got the following warning:

It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby.
