error: Setup script exited with error: command 'gcc' failed with exit status 1

I get the following error message when I tried to install tomahawk as following process of "How to install tomahawk"

Python's version is 2.4.3. tomahawk requires upper 2.4. My environments meets requirements.

Suddenly I remember that gcc troubles was solved by installing xxx-devel package.

I ran the following command.

  #]yum install python-devel

I could install tomahawk!
