It's not handled by receipts. If you were to use `port -d` to see  
debug information, you'd see that port always checks for a distfile's  
existence before downloading it. So, just drop the file in (with the  
right name) and you're good to go.

Yes, that's fine. I don't know anything about the particular library,  
but if it's not something everyone would have, it would be nice to  
confine its use to "platform darwin", test for its existence in pre- 
configure and, if it's not available, `return -code error "You don't  
have libblas"` (or a more detailed message).

Of course, that's only necessary if/when you release the portfile for  
general use, and from the downloads situation it sounds like that's  
not the case yet.
