[MacRuby-devel] Problem with MacGem install

Hi, I'm just starting to use MacRuby and I would like to be able to use OpenGL. So far I have been unable to install the GEM. I have just checked out the current MacRuby trunk (Mon 25 May) and after building it I get the following error: sudo macgem install ruby-opengl Password: macruby(37134,0x1037a5000) malloc: free_garbage: garbage ptr = 0x800031ca0, has non-zero refcount = 1 ERROR: While executing gem ... (RangeError) bignum too big to convert into `unsigned long long' Umm, is there a problem with the MacGem tool in the current drop or have I made a silly user error. Many thanks, Jonathan
