This was really painful. I consolidated numerous shared_ptr (TR1)
patches to a single big patch (including moving part of an existing
patch to it because the target needed yet another change).
Tested on FreeBSD 8/i386 and FreeBSD 10/amd64. This was previously
built on DragonFly with gcc 4.7, but libstdc++ incompatibilities caused
avogadro to break which eventually broken kde4 metapackage.
Those openbabel guys are long overdue for a new release, this was a bit
absurd although maybe some clever sed'ding could have reduced the patch
count.
Approved by: blanket (gcc5 & DF breakage)
