Heres my binary packages cleaning script. Its very simplistic but does the 
job.

#!/usr/bin/python

import os
import stat
import string

def samename(s0,s1):
  i=0
  for x in s0:
    if x in string.digits:
      break
    i+=1
  # same for s1
  j=0
  for x in s0:
    if x in string.digits:
      break
    j+=1
  return s0[:i]==s1[:j]

dirs=['All']
removed=[]
for dir in dirs:
  print 'Searching files'
  os.chdir('/usr/portage/packages/'+dir)
  list=os.listdir('.')
  list.sort()
  current=list[0]
  for x in list[1:]:
    if samename(current,x):
      time0=os.stat(current)[stat.ST_CTIME]
      time1=os.stat(x)[stat.ST_CTIME]
      if time0<time1:
        removed.append(current)
        os.remove(current)
        current=x
      else:
        removed.append(x)
        os.remove(x)
    else:
      current=x

print 'Removed',removed

print 'Searching for broken symlinks'
removed=[]
dirs=os.listdir('/usr/portage/packages/')
for dir in dirs:
  os.chdir('/usr/portage/packages/'+dir)
  list=os.listdir('.')
  for f in list:
    try:
      os.stat(f)
    except:
      if os.path.islink(f):
        removed.append(f)
        os.remove(f)

print 'Removed',removed
