Hello,

I am new to ruby and rubygame and have tried to get
http://rubygame.org/wiki/Generic_Game_Template to work as a starting
point, but I only get this error:

/usr/lib64/ruby/gems/1.8/gems/rubygame-2.5.3/lib/../ext/rubygame/rubygame_core.so: 

/usr/lib64/ruby/gems/1.8/gems/rubygame-2.5.3/lib/../ext/rubygame/rubygame_core.so: 

undefined symbol: SDL_FreeSurface -
/usr/lib64/ruby/gems/1.8/gems/rubygame-2.5.3/lib/../ext/rubygame/rubygame_core.so 

(LoadError)
from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`require'

`gem_original_require'
from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in
`require'
from main.rb:2

I have all dependencies for rubygame installed.
I use Gentoo Linux with a 32/64bit multilib profile. SDL, ruby and
rubygame are compiled as 64bit app.

I hope somebody can help me.

Greetings

Sebastian Beer
