R help - Jul 2015 - Seeing Build Commands when running "R CMD INSTALL <pkg>"

Hello,

I was trying to build a package from source (specifically the 'rzmq'
package) on the following platform:

Mac OS X 10.8.5 (Mountain Lion)
R: version 3.2.1
rzmq: version 0.7.7 (obtained from the github repo for this package)

The reason I want to build this from source is that there is no binary
available from CRAN for this version of rzmq for Mountain Lion (it is only
available for Maverick).

I'm using "R CMD INSTALL ..." to build the package. However, I get
some
errors. For now, I would just like to be able to see the exact raw commands
being sent to the compiler (gcc in my case), because I think the commands
aren't being set up correctly. Is there a way to do this?

Thank you!

Normally you will see those commands.  For example, if I try R CMD
INSTALL rgl_0.95.1252.tar.gz on a Mac I see

and so on.
