And two much less quick answers. My apologies.

It's ok. The macro is defined by autoconf, which I guess is used by  
both Ruby and QuantLib. There's no harm in redefining it.

Oh, yes, I remember. The asymmetry was introduced by me in order to  
make the life easier for the Debian maintainer, who wanted the module  
to be installed in the ruby lib. It's fixed now---and Dirk, if you're  
reading this, from now on you'll have to install by using

ruby setup.rb install --prefix=/whatever --debian

If --debian is not used, the "correct" behavior (that is, that  
suggested by Mark) is triggered.
