I'd start pulling apart the various sections of emerge to figure out 
how it accomplishes everything, but this code (while not guaranteed to 
be the best way) ought to be what you're after.
`
#!/usr/bin/python
import portage
global pdict; pdict = {}
global ptree
ptree = portage.portagetree()
temp = ptree.getallnodes()
for entry in temp:
     base = ''; package = ''
     (base, package) = string.split(entry, '/')
     if pdict.has_key(base):
         pdict[base].append(package)
     else:
         pdict[base] = [package]
for entry in pdict:
	print entry
`
While this is a bit more then you were after (you seemed after just 
categories), you can isolate out what you need by just grabbing the 
keys of pdict.  This leaves you w/ a hash, w/ lists of each package 
w/in each key.
