Hello, folks.

I’m experiencing some trouble trying to install rubygems-1.3.0 on  
Windows Vista (under cygwin). The same problem occurs when I try to  
instal 1.2.0. Here’s what happens:

$ ruby setup.rb  
mkdir -p /usr/lib/ruby/site\_ruby/1.8  
mkdir -p /usr/bin  
install -c -m 0644 rbconfig/datadir.rb  
/usr/lib/ruby/site\_ruby/1.8/rbconfig/datadir.rb  
(… lots of install commands …)  
install -c -m 0644 ubygems.rb /usr/lib/ruby/site\_ruby/1.8/ubygems.rb  
cp gem /cygdrive/c/Users/Pazu/AppData/Local/Temp/gem  
rm /cygdrive/c/Users/Pazu/AppData/Local/Temp/gem  
setup.rb:185:in `initialize': Permission denied - /cygdrive/c/Users/Pazu/AppData/Local/Temp/gem (Errno::EACCES) from setup.rb:185:in`open’  
from setup.rb:185  
from setup.rb:170:in `each' from setup.rb:170 from setup.rb:165:in`chdir’  
from setup.rb:165

I’ve tried disabling UAC, but the results are the same. I’ve checked  
permissions for the Temp directory, and it’s definitely writable. I’m at  
a lost about what to try next, any help is appreciated.

Thanks!

– Pazu

Whatever the problem was, seems to be fixed in trunk. I’ve downloaded  
the most recent rubygems code from subversion, and it installed OK.
