gem install rbczmq fails under Windows

Using 3.3.6 with ridk installed, I get the following error when trying to install the

 gem install rbczmq
Building native extensions. This could take a while...
ERROR:  Error installing rbczmq:

Doing a bit more investigation, if I run autogen.sh manually, using ridk exec bash -c ./autogen.sh then it does indeed run.

The extconf.rb in rbczmq-1.7.9 is trying to execute autogen.sh directly. Perhaps it needs Windows specific logic to run autogen.sh through bash?
