Everything is installed from the official Ubuntu repositories.
libboost version 1.40, non-modified ld.so.conf files

Is boost installed, from packages? which version? have you installed
your own libboost from sources?
Any customizations you've made of /etc/ld.so.conf ?

I am using the stock 0.7 version of mapnik, that comes with Ubuntu 10.04.
libtool seems to report "file not found" whenever some symbols can
not be resolved.
Loading the plugins manually gives the following error messages:
Cannot load library /usr/lib/mapnik/0.7/input/kismet.input:

It seems these dependencies are missing from the plugins, e.g.:
ldd /usr/lib/mapnik/0.7/input/kismet.input
linux-vdso.so.1 => (0x00007fff243ff000)

It seems strange that I can load these plugins from a normal program,
but not from a shared library.

I'd guess there is some easy to understand library/linking error
that is being experienced by libtool but not reported. Calling ldd
on the plugins might give clues. This error can happen under normal
circumstances when libtool,via libmapnik, tries to load plugins that
are themselves linking to an old, non-existant, or duplicate
libmapnik. In this case recompiling each plugin fixing things.

I have a shared C++ library that uses mapnik. This library is loaded
dynamically from my main program.
When registering the input plugins with mapnik libtool throws an
error. This error disappears when compiling the library a a static
executable.
The library is realized as a QtPlugin library.
System: Ubuntu 10.4, amd_64
Mapnik: 0.7
Code:
mapnik::datasource_cache::instance()->register_datasources(
"/usr/lib/mapnik/0.7/input/" );
