well, no and yes.
It does include a rudimentary 'runsocks'
shell script which re-orders the
dynamic library path which should accomplish
what you want.
However, that script doesn't know about
OSX but that should be pretty trivial to
change.
If you have the libsocks.dylib correctly,
then you should be able to specify
it using DYLD_LIBRARY_PATH but there
are restrictions. See 'man dyld'
