md5 sum of rubygems-0.9.0.tgz: 5d496e1f415b8b4033ab867f01d1161f (174321 
bytes)

of note in tar -zxvf rubygems-0.9.0.tgz: both the Rakefile and 
gem_commands.rb show up twice:

rubygems-0.9.0/._Rakefile
rubygems-0.9.0/Rakefile

rubygems-0.9.0/lib/rubygems/._gem_commands.rb
rubygems-0.9.0/lib/rubygems/gem_commands.rb

of note in ls -lr of the original attempted install: both Rakefile and 
gem_commands.rb show up twice, like this:
.:
-rwxr-xr-x   1 vorn  staff       0 17 Dec 15:06 Rakefile
-rw-r--r--   1 vorn  staff    9330 28 Jun 07:42 Rakefile.1

./lib/rubygems:
-rw-r--r--  1 vorn  staff  41032 21 Jun 20:44 gem_commands.1.rb
-rwxr-xr-x  1 vorn  staff      0 17 Dec 15:06 gem_commands.rb

I'm not sure, but I believe the original decompression (though I don't 
recall how it was done - perhaps my browser did it for me? it's the 
latest release Safari under 10.3.9) "cleaned up" the filenames of 
lib/rubygems/._gem_commands.rb and of ._Rakefile, then renamed the 
subsequent "real" ones in usual Mac style so as not to stomp.

._gem_commands.rb and ._Rakefile are identical binary files.  file says 
it's an "AppleDouble encoded Macintosh file".  Here is a hexdump.
0000000 0005 1607 0002 0000 4d61 6320 4f53 2058
0000010 2020 2020 2020 2020 0002 0000 0009 0000
0000020 0032 0000 0020 0000 0002 0000 0052 0000
0000030 0000 0000 0000 454d 4178 0000 0000 0000
0000040 0000 0000 0000 0000 0000 0000 0000 0000

I will now go post all this under the bug report too.  My proposed 
solution: if these two files are not necessary for the installation, 
remove them!
