 Current trunk version (rev. 305) fails to install on my computer. I'm
 running OSX 10.5.3, I have version 0.2 installed from the binary package
 and tried to install the latest version from source. It compiles
 successfully, but sudo rake install throws such exception:

 I've investigated this error, and it seems that the call "File.join(dest,
 File.basename(src))" in fu_each_src_dest0 function in fileutils.rb doesn't
 always return what it should. In this case src = 'macruby', dest =
 '/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/bin/', but the
 result is '/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/bin/'
 instead of
 '/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/bin/macruby'. I
 ended up in the code of rb_file_join function in file.c, where strings are
 concatenated using CFStringAppend, but in this case CFStringAppend only
 appends the first string (.../usr/bin), and appending another (macruby)
 doesn't work, I don't know why.

 I found that this area of code was modified in changesets 213 and 214, and
 when I reverted those changes, the installation passed that point at which
 it previously failed (although it still failed later on another path).

 That's all I was able to figure out, I hope this helps...
