​Holy cow! I applaud your patience. Even on the slowest filesystem it

​I do not currently have or use El Capitan (I may upgrade one of my Macs
soon), but others use it just fine. I *suspect* what is happening is that
the XCode license has not yet been accepted. This typically happens the
first time you run "make" or a related command. A prompt pops up on the
command-line and asks if you accept Apple's EULA.

If you hadn't done this before, it probably did that while running the
NetCDF configure script. Which meant for the past 10 hours, your Mac was
waiting for the NetCDF configure script to accept Apple's EULA... It's an
incredibly irritating "feature" in Apple's newer development tools.

The solution is to run "make" by itself somewhere in the terminal. That
should pop up with a dialog in the terminal where you "read" the EULA and
accept it. Once you do this, it should not happen again (try reconfiguring
AmberTools and see if it works).
