-------------------------+---------------------------------------------
 I am currently working to compile a project using gobject introspection
 (ufo : https://github.com/ufo-kit/ufo-core.git).

 This package uses gobject introspection for its python interface. In the
 build process g-ir-scanner is runned on the source to extract API
 information but fails with message :
 {{{

 dyld: Symbol not found: _iconv

 }}}

 As I am not an expert in GIR, my understanding is likely (partly) wrong :

 gi-r-scanner is producing an executable that is self-introspecting for
 generating the API file (in GIR format). But this executable is linked to
 the wrong version either of libarchive or libiconv. My guess is that both
 these should be taken from the MacPorts /opt/local/lib (rather than
 libarchive from the system and libiconv from MacPorts)

 This is running MacOS 10.15.7 (Catalina) on a MBP 16p
