I see you've now uploaded this, and it seems to fix my problem building
the mapnik python bindings[1]. Thanks!

However, it looks to be like the shlibs file needs updating. My
python-mapnik package is linked against the py25 library:

dom at callisto:~$ ldd /usr/lib/python2.5/site-packages/mapnik/_mapnik.so|grep boost_python
        libboost_python-gcc42-mt-1_34_1-py25.so.1.34.1 => /usr/lib/libboost_python-gcc42-mt-1_34_1-py25.so.1.34.1 (0xb7b2c000)

yet my package still has a Depends line (generated from shlibdeps) of
libboost-python1.34.1 (>= 1.34.1-2.1)

which I don't think is going to work, since that library only appeared
in libboost-python1.34.1 1.34.1-8. Hence upgrades will potentially

Have I done something wrong, or is this analysis correct and the shlibs
file needs updating? If that latter, let me know if a report in the
BTS[2] would be (more) useful.
