I'm not very founded to split up boost more than it already is. The standard 
package contains 28 library files of 150k average size totalling appr. 4.5Mb.
I can't see how fragmenting this package even further will be of any benefit.

I've just completed several packages for GnuRadio and contemplated to submit 
these as soon as wxGTK and py-wxWindows get updated to their corresponding
