not sure yet.

yes, but see (1).

I am not quite finished with implementing what's behind in add_library 
method, and so, it may not work yet (I had a working version before 
cvs->svn but this version is against cvs repository that I need to apply 
to svn).

The idea behind this strange naming convention (that may change to a 
better one) is that one can build/install pure libraries that will be 
available to different scipy packages. A classical example is blas/lapack 
libraries that are used by many extension modules from different packages.
The problem is to find out how setup scripts of packages can find the 
location of such libraries that may be in completely different branch of 
a directory tree and using this naming convention is one of the ways to 
specify libraries locations. I know, it's ugly and I don't like it myself 
but that's just a side result of a process for looking a right 

I'll try to find some time to review the add_library stuff as soon as
