There is some strangeness with the boost libraries. I've got it built on
debian but i had to make scons changes.

Firstly you were specifying the soname to link to (well not quite the
soname but a compiler specific version of the library), which is a bit
naughty.

This is what i changed in SConstruct

On a well managed distro I presume that the actual libboost installed
reflected the gcc compiler version selected. So on debian if i update
alternatives to use gcc-3.4 i get the correct boost libraries for
anything i build.

In the libs package you should probably supply a
libboost_program_options.so that is simlinked to your actual
libboost_program_options-gcc34-mt and probably change the gcc command to
gcc-3.4 to force non standalone users to use 3.4 or else boost hell will
let loose.

The only thing i can think of for your problem is that your gcc and your
boost libraries don't match.
