Hi and thanks for stepping up and revitalizing this awesome project!

Got a checkout done and was able to build on Fedora 20 (no such luck 
with the previous 4.0 alphas),

yum install autogen-libopts-devel-5.18-1.fc20.x86_64
./configure --enable-dynamic-link --disable-local-libopts

+ a build fix (remains of didsig in the code which had been refactored) 
did the trick, pull request sent

Some notes:

Some old annoyances are still around ( 
https://github.com/synfinatic/tcpreplay/pull/9 ), now trying to figure 
out how they apply to the new code base and fix them :-). They're quite 
easy to run into, run tcpreplay
with --loop 0 with really small (1-10 packets is typical)  pcaps.

Used to run like:
tcpreplay -K --stats 1 -i virbr0 -M 50 --loop 0 out.pcap

where ^C didn't actually exit. Fixed in pull request.

The rest still investigating how they apply.
I'm running tcpreplay in a small wrapper written in nodejs (simplified 
option set and supports start from 100Mbps and slow down to 0 Mbps, then 
exits + dump stats out in JSON), hence the fflush after printing stats.

Noticed -K is missing, replaced with --preload-pcap... High cpu use 
despite low packet rate, will investigate.
