Your package cgal4 fails to build with this error:
Boost version: 1.35.0
Boost include path: /sw/include/boost-1_35
The following Boost libraries could not be found:
'fink list -i boost' says that I have boost1.35.python25,
boost1.35.python25-shlibs, and boost1.35.python26-shlibs installed, none
of which have the boost_thread library, but are listed as permitted
under cgal4's (Build)Depends field.
Manually installing boost1.35.nopython-shlibs allows the build to
finish. The (Build)Depends fields need to be fixed to point to a single
package that actually provides the boost_thread library. Assuming cgal4
actually works with them, boost1.41.cmake-shlibs or
boost1.46.cmake-shlibs could also be used.
