That skip in SeqIO.t is new and I simply didn't think of them as 
important enough to make anyone install them or include them in t/lib.

I'd go ahead and add those modules, but like I say, it may make more 
sense just to use is_deeply(), removing the dependency on 
Algorithm::Diff and IO::ScalarArray completely.
