When you require something, you do not require a gem. You require
either a .rb (ruby source) file or a .so (library) file. 

Ruby searches these files in standard directories, plus in those
included in environment RUBYLIB. Look at where, under
/home/anisimovich/gems, the weibo.rb or weibo.so file is, and add that
directory to the content of RUBYLIB.
