Yes, that was the problem. I spend a few hours to figure out how to make my system to perceive gfortran, then compiled the source codes 0.3.0 pre-release. Then all work fine now.
I think it would be a good idea to provide pre-release version as a binary. A simple overnight automatic build system can be used to upload the most recent pre-release version to the website easily, weekly (or even daily) basis (though must be after success of automatic testing of the core and packages, of course), so that new comers don't have to get into 'compiling' from the source codes. Compiling IS a major barrier. And, specifically for the packages, the best would be, of course, better package version control system, that can handle the julia binary version and the package version at the same time. Anyway, thanks for help. I'll try julia soon.
