I tried to install the pecl oauth extension on my debian box today with the command:

pecl install Oauth-0.99.9

and ran into a few problems:

1. ERROR: `phpize’ failed – Solution:  apt-get install php5-dev
2. sh: make: command not found – Solution:  apt-get install make
3. make: *** [oauth.lo] Error 1 – Solution:   apt-get install libcurl4-openssl-dev

After that everything installed fine.
