This post is a further response to the thread started by Henrique
Andrade in November of last year, in
http://lists.wfu.edu/pipermail/gretl-users/2016-November/012194.html
I'm afraid that remained unresolved at the time, but I can now report
that I've made several small changes to the gretl configuration and
build files which should make things smoother. More substantially,
there's new material at
https://sourceforge.net/projects/gretl/files/osx-testing/
that should be helpful: apparatus to build gretl using just Apple's
Xcode Command Line Tools plus a new "gretl-dev" framework, available
as a dmg file. This method does not require a third-party package
manager such as MacPorts or Homebrew.
The full story is in gretl-osx-howto.pdf at the above location. This
document also gives a recipe for building gnuplot for use with gretl
on MacOS, and even describes how to build the gretl-dev framework
yourself (with the help of some shell scripts) in case anyone is
feeling adventurous.
