Re: [gtk-osx-users] New build system

[John Ralls <jralls ceridwen us>]

The second one is easy: gobject-introspection is trying to link against the PyEnv libpython. PyEnv naturally 
sets macosx-version-min to the running MacOS. If you want to set macosx-version-min earlier you need to build 
python3 so that there's a libpython with the same linkage flags.

The pyenv-based setup doesn't change the actual builds: The same environment variables and compiler flags are 
set, so ISTM that differences in dylib layout must be due to Apple changing the linker. I have a collection 
of MacOS VMs that I use to build GnuCash and Gramps for distribution. On the 10.9 VM using the pyenv-based 
setup I find that libintl *does* have the the LC_VERSION_MIN_MACOSX setting.

John Ralls
