I do this all in one go by rendering to a tilted equirectangular 
with the poles and seams in the middle of the image:

I ought to put a release on CPAN.  Until then I've just uploaded a 
snapshot here:

http://panotools.sourceforge.net/snapshots/

There are some example scripts included to give you an idea how it 
works.

I have an (uncommited) script which does more or less what Yuval is 
doing, except to solve the problem of sharpening an equirectangular.  
It extracts the nadir and zenith as fisheyes, applies an unsharp 
mask to all three and recombines them.  It isn't perfect, but I get 
much better results than sharpening cubefaces (which really really 
really doesn't work).
