Hi

Has some managed to install Ruby Debugger with gems package manager ?

I was trying to install the debugger with command “gem install ruby-  
debug”

=====================================================================  
C:\ruby\>gem install ruby-debug  
Building native extensions. This could take a while…  
ERROR: While executing gem … (RuntimeError)  
Error instaling ruby-debug:  
ERROR: Failed to build gem native extension.

ruby extconf.rb install ruby-debug  
creating Makefile

nmake  
‘nmake’ is not recognized as an internal or external command,  
operable program or batch file.

Gem files will remain installed in c:/ruby/lib/ruby/gems/1.8/gems/ruby-  
debug-bas  
e-0.10.0 for inspection.  
Results logged to c:/ruby/lib/ruby/gems/1.8/gems/ruby-debug-  
base-0.10.0/ext/gem\_  
make.out

=====================================================================

Is there a way to fix this ?  
Please help.
