I really don't know, I think you know more about this
than anybody now. :)

What you could do is construct a script
to check the library dependencies of the object files.

Usually the command is ldd, like:

ldd /usr/lib/python2.3/site-packages/PIL/_imaging.so
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x6ff65000)
        libz.so.1 => /usr/lib/libz.so.1 (0x0f7b0000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x0fd50000)
        libc.so.6 => /lib/libc.so.6 (0x0fe70000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x08000000

No idea, this seems complicated.

Can you see something from the code.
I mean because of this being so complicated I just hope that
we improve the font handling for 0.7. :)
