you could probably use arb, it does alignements and phylogenetic trees,
with proteins and dna, there are so many feautures that i imagine that
it can also do things as you want them, you must trie to find out.
arb is free for linux, i guess it would also work on unix (i apriciate
your two OS options, me i have to work the whole f. day with wintel crap
(and 1 linux/amd machine of course)).
