The latest version doesn't need a dep file: $ ldd /usr/local/lib/libproxy.so
linux-gate.so.1 => (0xf77c5000)
libpthread.so.0 => /lib/libpthread.so.0 (0xf7774000)
libdl.so.2 => /lib/libdl.so.2 (0xf7770000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xf76ae000)
libm.so.6 => /lib/libm.so.6 (0xf768b000)
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xf7674000)
libc.so.6 => /lib/libc.so.6 (0xf7569000)
/lib/ld-linux.so.2 (0xf77c6000)
..but it looks like the tree file needs an update
