When I tried to install the Library PIL on a Ubuntu 8.04 where I had installed Python 2.6 I got:

running build_ext
building ‘_imagingtk’ extension

_imagingtk.c:55: warning: implicit declaration of function ‘TkImaging_Init’
error: command ‘gcc’ failed with exit status 1
I’d founded the file ‘tk.h‘ on ‘/usr/include/tcl8.4‘ and after a look at the setup.py file I changed the line number 41 from:
TCL_ROOT = None
to
TCL_ROOT = “/usr/include/tcl8.4”
Now you can run your ‘python setup.py install’ again and get PIL working!
Note: You may perhaps have to install the tk-dev and tcl-dev packages before running the setup.py. I’d already had these packages, so I’m not sure about it.
On Ubuntu run:
apt-get install tk-dev tcl-dev
