Błąd podczas instalowania adaptera dm-mysql

Question

Jestem nowym użytkownikiem Ruby. Zainstalowałem DataMappera i próbuję zainstalować gem dm-mysql-adapter-1.0.2. Ale kiedy próbuję zainstalować, pojawia się poniższy błąd. Używam ubuntu OS.

vinoth@vinoth-laptop:~/Downloads$ gem install dm-mysql-adapter-1.0.2 -- --with-mysql-     lib=/usr/lib/mysql -- --with-mysql-conf=/usr/bin/mysql 
WARNING: Installing to ~/.gem since /home/vinoth/gems and 
/home/vinoth/gems/bin aren't both writable. 
WARNING: You don't have /home/vinoth/.gem/ruby/1.8/bin in your PATH,

Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers. Check the mkmf.log file for more 
details. You may need configuration options. 

Provided configuration options: 
    --with-opt-dir 
    --without-opt-dir 
    --with-opt-include 
    --without-opt-include=${opt-dir}/include 
    --with-opt-lib 
    --without-opt-lib=${opt-dir}/lib 
    - ........ 


Gem files will remain installed in /home/vinoth/.gem/ruby/1.8/gems/do_mysql-0.10.2 for inspection. 
Results logged to /home/vinoth/.gem/ruby/1.8/gems/do_mysql-0.10.2/ext/do_mysql/gem_make.out 

Czy brakuje mi czegoś?

Dodatkowe informacje.
