Comment(by dweber@…):

 Can't find TFM on 'option'.  Is it a macports tcl extension?  The only
 thing I found was the option database for tk, probably not what your
 talking about.

 Here's a concrete example of what I'm doing in vtk-devel - any tips on how
 to tidy this up would be great!  The idea is to provide two variants for
 python wrapping, one for py25 and another for py26 (and they must
 conflict, but only because of configure and build issues, not installation
 issues).

 {{{

 variant py25 conflicts py26 requires shared description {python 2.5
 wrapper} {
     set pyver        2.5
     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}
     configure.args-delete \

     configure.args-append \
         -DVTK_WRAP_PYTHON:BOOL=ON \

         -DPYTHON_LIBRARY:FILEPATH=${prefix}/lib/lib${python}.dylib \
         -DPYTHON_DEBUG_LIBRARY:FILEPATH=${prefix}/lib/lib${python}.dylib \
         -DPYTHON_EXECUTABLE:FILEPATH=${prefix}/bin/${python} \
         -DVTK_PYTHON_SETUP_ARGS:STRING='--prefix=${prefix}
 --root=${destroot}'
         # The VTK_PYTHON_SETUP_ARGS *MUST* be in single quotes
 }

 variant py26 conflicts py25 requires shared description {python 2.6
 wrapper} {
     set pyver        2.6
     set python       python${pyver}
     set pyport       [join [lrange [split ${python} .] 0 1] ""]

         # For 2.6, it needs to be installed into ${pyframe}/lib/${python

         # The VTK_PYTHON_SETUP_ARGS *MUST* be in single quotes
     post-destroot {
         # Redefine all the python variables in this clause (they are not

         # through from the definitions above in the variant).
         set pyver        2.6
