Thank you for all your replies.

So,what do you suggest me do if I want to do alignment with external tools like clustawl or dpalign? In the current distribution of BioPerl, ext package is still required to do this, I am afraid.
Thank you.

And, with that in mind, frankly I would be much more amenable to supporting XS (or similar) interfaces to common bioinformatics libraries (Bio::DB::Sam as an example) than ones specifically designed with bioperl in mind.  The latter (bioperl-ext) have significantly bit-rotted to the point I'm not sure whether they would be worth keeping around.
