graphics/povray37: Fix build on clang, support stage

The main problem with building this port with clang was the use of
shared_ptr without the boost namespace which clashes with libc++.  This
occurs in numerous places but luckly sed can fix most of them save for
a few files that inconsistently used boost names.

It was also missing an explicit link to libboost_system [1]
