- In Eclipse's menu, go to "Window" > "Preferences" > "PyDev" > 
"Interpreter - Python"
- In the "Python interpreters" list, select the Python interpreter you 
want to configure
  (this example assumes Python 2.7 installed into C:\bin\Python27, 
adjust as needed)
- In the bottom notebook, go to the "Environment" tab and click the 
"New..." button
- Set "Name:" to PATH and "Value:" to 
C:\bin\Python27\Lib\site-packages\gtk-2.0\runtime\bin;%PATH%
  and click the "OK" button. The "Value:" part points to the bin 
directory of your GTK+
  bundle (this example assumes the PyGTK All-in-one installer which 
already comes
  with an appropriate GTK+ bundle out of the box).
- In the bottom notebook, go to the "Forced Builtins" tab and click the 
"New..." button
- Set "Builtin to add" to 
cairo,glib,gobject,gio,atk,pango,pangocairo,gtk,gtk.gdk,rsvg,gtksourceview2,goocanvas
  and click the "OK" button.
- Back in the "Preferences" dialog, click the "OK" button and wait for 
PyDev to update its
  symbol database.

So, the first part (setting PATH) answers your question, the second
part (setting forced builtins) ensures PyDev's more advanced features
like code completion function correctly for PyGTK's C extension modules
and works for Eclipse on Windows and Linux equally well.

Note: sometimes PyDev fails to notice its symbol database has been 
updated
and various combinations of restarting Eclipse, right-clicking your 
PyDev project
and selecting "PyDev" > "Remove error markers" and "PyDev" > "Code 
analysis" are
needed before the Python editor stops showing "Unresolved import" 
errors etc...
Through the years this seems to have happened for some combinations of
the Eclipse platform and PyDev version. It always eventually starts 
working
though and once it does, PyDev is a joy to use. Especially its 
debugger, which
has nothing even remotely competing with it imho :)
