 Can we make variant variables carry through into the post-destroot stage
 definition within the variant (such that variables defined within the
 variant over-ride any global variables)?

 For example:

 {{{
 variant python26 {
     set pyver    2.6
     set python   python${pyver}
     set pyport   [join [lrange [split ${python} .] 0 1] ""]
     set pyframe
 ${prefix}/Library/Frameworks/Python.framework/Versions/${pyver}

     depends_lib-append port:${pyport}

     post-destroot {
         set pyPackage ${destroot}${pyframe}/lib/${python}/site-
 packages/THISPACKAGE
     }
 }
 }}}


 In this mock-up example, the depends-lib will get the ${pyport} but
 anything within the post-destroot will not see any of the python variables
 defined in the variant.  All of those variables have to be either global
 or set within the post-destroot clause (within the variant).
