compilation terminated.
error: Setup script exited with error: command 'gcc' failed with exit status 1
sorry for the catalan in here but El fitxer o directori no existeix means that the file doesn't exist
i think that i perhaps miss something or i don't know
does anyone else have the same problem? or know how to install it correctly?

The header files are typically installed with Python. On Unix, these are located in the directories prefix/include/pythonversion/ and exec_prefix/include/pythonversion/ , where prefix and exec_prefix are defined by the corresponding parameters to Python's configure script and version is '%d.
Python.h is nothing but a header file. It is used by gcc to build applications. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications.
depending on how you installed python, you may need to get the dev files as well (if you installed with apt-get or Synaptic).
sudo apt-get install python-dev
or maybe
sudo apt-get install python2.6-dev #substitute your python version here...
Note that this is necessary if you need to install any C extensions to Cpython.
