Actually... :)

bit easier, abusing portage's own functionality.

python -c $'
import portage, time
target=long(time.strftime("%s",time.gmtime())) - 24*60*60
pdb=portage.portdb
for cp in pdb.cp_all():
	for cpv in pdb.cp_list(cp):
		flagged=False
		try:	mtime, eclasses = pdb.aux_get(cpv,["_mtime_","INHERITED"])
		except SystemExit:	raise
		except:	continue
		if mtime >= target:	flagged=True
		else:
			try:
				for e in eclasses.split():
					if pdb.eclassdb.eclasses[e][1] >= target:
						flagged=True
						break
			except KeyError:	flagged=True
		if flagged:	print cpv
