EPEL5 owns python26 now, can iotop be ported to EPEL5 now?

Hello all,
Per the EPEL meeting last week we are attempting to get iotop working for EL5. The issue is that iotop requires Python >= 2.5 in order to use the builtin netlink support (of the socket module). That said, there is also a fallback on the '_netlink C module':
From /usr/lib/python2.4/site-packages/iotop/netlink.py:
#------------------------------------------------ try: # try to use python 2.5's netlink support _dummysock = socket.socket(socket.AF_NETLINK, socket.SOCK_RAW, 0) _dummysock.bind((0, 0)) del _dummysock def _nl_bind(descriptor, addr): descriptor.bind(addr) def _nl_getsockname(descriptor): return descriptor.getsockname() def _nl_send(descriptor, msg): descriptor.send(msg) def _nl_recv(descriptor, bufs=16384): return descriptor.recvfrom(bufs) except socket.error: # or fall back to the _netlink C module try: import _netlink except ImportError: raise ImportError("This is neither python 2.5 nor is " "the _netlink C module available!") def _nl_bind(descriptor, addr): _netlink.bind(descriptor.fileno(), addr[1]) def _nl_getsockname(descriptor): return _netlink.getsockname(descriptor.fileno()) def _nl_send(descriptor, msg): _netlink.send(descriptor.fileno(), msg) def _nl_recv(descriptor, bufs=16384): return _netlink.recvfrom(descriptor.fileno(), bufs) #------------------------------------------------
I can't figure out where the '_netlink C module' would be provided, as I was hoping to implement that if possible. All Google hits seem to reference this code.
Any ideas?
Hmm. No. :) Other than askin the iotop guys where they got that _netlink module from or checking on one of the python development lists.
I wonder how hard it would be to rip out the python 2.5+ socket module as an external package and either install it explicitly with iostat in some non-conflicting way or rename it and install it in some non-conflicting way that could be used by a patched iostat...
