The symbol mentioned should be found in the libxml2.so library file
(which I discovered by running nm on the static libxml2.a file). On my
Ubuntu system, if I run the ldd program on the libxml2mod.so file (in
a different place to where yours lives), I get the following results:

  ldd /var/lib/python-support/python2.5/libxml2mod.so
        linux-gate.so.1 =>  (0xffffe000)
        libxml2.so.2 => /usr/lib/libxml2.so.2 (0xb7e0b000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7cca000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7cc5000)
        libz.so.1 => /usr/lib/libz.so.1 (0xb7cb1000)
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7c8a000)
        /lib/ld-linux.so.2 (0x80000000)

I suggest you run ldd on /usr/local/lib/python2.5/site-packages/
libxml2mod.so for each user and see what it tells you. Perhaps there
are permissions issues on the libxml2.so files, wherever they are
installed, or there's a LD_LIBRARY_PATH (or equivalent) setting that
one user has that the other doesn't.
