Doesn't that also lists indirect dependencies (575 of them)?  After 
some experimentation at the REPL, I came up with the following to 
find only packages directly depending on boost:

(use-modules
  (srfi srfi-1)
  (guix packages)
  (gnu packages)
  (gnu packages boost)
  (guix scripts refresh))

(define (depends-on-boost pkg)
   (any (lambda (p) (eq? p boost))
        (map cadr (append (package-inputs pkg)
                          (package-propagated-inputs pkg)
                          (package-native-inputs pkg)))))

(let ((all-deps (filter depends-on-boost (fold-packages cons '()))))
   (format (current-output-port)
           "~{~a~^~%~}~%" (map package-name all-deps)))

Leading to the 97 dependencies in the attached file.

Is that approach correct?  There are also 3 packages which have boost 
as a propagated input (mdds, gpgmepp and librevenge).  That could 
lead to further packages depending on boost, which are missing from 
the list, but for now I'll assume that such cases are rare.

Meanwhile I'll try to build those 97 packages, stay tuned ;-)
