Naturally that's what I tried to do first :)
And since I need DNS, I included pcap requirement.

Here is a compilation error with 4.8.1

make[4]: Entering directory 
`/usr/src/redhat/BUILD/collectd-4.8.1/src/libcollectdclient'

{

and

__attribute__((nonnull (1, 2)))
static char *lcc_strescape (char *dest, const char *src, size_t dest_size) 
/* {{{ */
{

which I can comment out the __attribute__ line

then later:

I couldn't fix this though.
