I have a workaround for a small problem with rake 0.8.7 on Windows, in case anyone else is having a problem with it.
The symptom is that anything you try to do with rake gives you an error message which contains the text
<path>/ruby/bin/rake:23:in `load': no such file to load -- "file/name/goes/here"
Note the " " marks around the file name.
Rake calls Gem.bin_path which puts an extra set of "" marks around the string it returns (possibly only if the path has a space in it). This breaks load, so the last line of <path>ruby/bin/rake does not run.
A workaround for this is to change it to be
load Gem.bin_path('rake', 'rake', version).gsub("\"","")
(although it may be better to hunt down the problem in Gem.bin_path)
