[R-SIG-Mac] Installing rzmq package

[Stephen Eglen]

Dear all,

Does anyone have any insight into installing `rzmq` either from CRAN or
from github?  the CRAN page notes the dependency on the zeromq
libraries:

https://cran.r-project.org/web/packages/rzmq/index.html

I have installed `zeromq` via homebrew, but then get a mismatch in
dynamic library versions; CRAN package expects libzmq.4.dylib and
homebrew installed libzmq.5.dylib.  This has been noted in the following
issue:

https://github.com/armstrtw/rzmq/issues/18

and so the .so reference in the CRAN package can be fixed via the call
to `install_name_tool`

But does anyone have any advice on fixing this problem?  Would it be to
get the mac R package to install the zeromq libraries?
