rpm is fixed, it is not statically linked anymore.
librpm-4.2.so => /usr/lib/librpm-4.2.so (0x40032000)
librpmdb-4.2.so => /usr/lib/librpmdb-4.2.so (0x40087000)
librpmio-4.2.so => /usr/lib/librpmio-4.2.so (0x40166000)
libpopt.so.0 => /usr/lib/libpopt.so.0 (0x401c4000)
libelf.so.1 => /usr/lib/libelf.so.1 (0x401cc000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x401dc000)
librt.so.1 => /lib/tls/librt.so.1 (0x401ea000)
libbz2.so.1 => /usr/lib/libbz2.so.1 (0x401fe000)
libc.so.6 => /lib/tls/libc.so.6 (0x00e80000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
But I'm afraid there are other statically linked apps which use NSS,
so the dlopen from dlopen either needs to be avoided, or fixed.
