This will work because /usr/include is part of the default search

You need to tell the linker what libraries you want to link to.  You
might have to tell it where the .so is, if it isn't in the default
search path.  I think it should be in /usr/lib which is in the default
search path.  If I assume that the library is "libpython.so" then you
want the following gcc command line :

    gcc -I /usr/include/python2.1 -lpython hello.c
