cygwin中的Ruby DevKit不工作

Question

我試圖安裝需要安裝ruby DevKit的gem。 E.g：

gem install sqlite3 

這是輸出：

Temporarily enhancing PATH to include DevKit... 
Building native extensions. This could take a while... 
ERROR: Error installing sqlite3: 
ERROR: Failed to build gem native extension. 

/usr/local/bin/ruby.exe extconf.rb

make: gcc: Command not found 
make: *** [backup.o] Error 127 


Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/sqlite3-1.3.3 for inspection. 
Results logged to /usr/local/lib/ruby/gems/1.9.1/gems/sqlite3-1.3.3/ext/sqlite3/gem_make.out 

我有安裝make和gcc的，不明白爲什麼它抱怨命令無法找到。

這種情況不僅發生在我嘗試安裝sqlite3 gem，而且還需要安裝其他需要de devkit的gem。

DevKit用於YARV的MingW端口，而不是Cygwin端口。 Cygwin端口不需要DevKit，因爲Cygwin本身已經包含了所有必要的工具，庫和頭文件。
