We might also consider building the xapian index along with the package
cache. But, that does come with the cost of slowing down profile builds
slightly.

I'm not a big fan of SWIG either. But, the main reason guile-xapian uses
SWIG is because that's what upstream
https://github.com/xapian/xapian/tree/master/xapian-bindings provides us
with. I'm not saying it is the best situation, but it is what it is, I
guess.

Regards,
Arun
