Packages are perfectly portable as that is a main goal of Boost. So in that
sense the question is misdirected; few things are as 'portable' as
Boost.
The issue is more about how to ensure _binary libraries_ are found if needed
for linking. Boost itself is a (vast) collection of libraries (in the
abstract sense of 'packages'), and only a few employ (binary) libraries.
Many
can be used in a pure template sense so that only headers are needed at
compile time.
That is what Jay refers to above: we are contemplating creating a common
boost headers package to be used by the half dozen packages shipping their
own copies.

Back to the issue of finding Boost libraries: you can study existing
packages. RQuantLib for example needs to use a configure snippet and a
special case on Windows.
But in case you just want to use templates, look at RcppBDT --- an example
package using Rcpp and its 'Rcpp modules' feature to easily access Boost
Date_Time. It by choise does not use Date Time string parsing and formatting
and hence uses only templated headers---and as such is easily buildable on
Windows, OS X, ... as the CRAN page http://cran.r-project.org/package=RcppBDT
and its links show.
Hope this helps, Dirk
