Nick,
ABI incompatible binaries, perhaps? Both boost-* and mapnik must be
built with the same c++ compiler.
Could you check :
g++ -v
and
ldd /usr/lib/libboost_thread*.so
ldd /path/to/libmapnik.so
ldd /path/to/mapnik/input/postgis.so
to see if all the above is linking to the same c++ runtime library
libstdc++.so.6
I guess I can login into dev and have a look around tomorrow.
Cheers,
Artem
