Yes, the issue was resolved and was able to install the plugin.
However, we have two 10 gig NICs on the Bro worker node and netmap cannot allocate memory for the second interface.
[root at sec-bro04 ]# lb -i em1 -B 1024 -p broem1:10
881.534306 main  interface is em1
881.534384 main  requested 1024 extra buffers
883.371747 main  successfully opened netmap:em1 (tx rings: 512)
883.371818 main  obtained 1024 extra buffers
[root at sec-bro04 ]# lb -i em2 -B 1024 -p broem2:10
014.454468 main  interface is em2
014.454555 main  requested 1024 extra buffers
014.501811 nm_open  NIOCREGIF failed: Cannot allocate memory em2
014.501828 main  cannot open netmap:em2

Unfortunately in the plugin that comes with 2.5, you need netmap installed on the system you're building on. We're going to be making changes for the 2.6 release so that nothing is required from netmap at build time and it is just built by default and included in Bro.
If you install netmap, does the problem go away?
