trunk is an svn thing which has no parallel in git.  I don't see trunk mentioned in the current instructions.

I changed the moves to copies.  It is the original file that needs to be copied.  I prefer copying to linking for 
clarity's sake, but whatever works to make the libode.so reference valid in the file system if fine, of course.

If uname says 32 bits then you have the 32 bit version of the OS installed.
