Log Message:
Don't create the mass of symlinks for the headers as they're not used
by FLTK packages.  Packages know to use <FL/*.H> for fltk>=1.1, which
we already require via BUILDLINK_DEPENDS.fltk.  This fixes the build
on Darwin where the symlinks were, by default, not created and which
subsequently broke the PLIST.  Bump the PKGREVISION to 2.
