Cant build gobject-introspection

Decided to build new system (svn as of 2019-09-23) and try out non-systemd version with logind + pam. I've never built gobject-introspection before because i never build gnome, but, with current libsecret and upcoming version of gimp requiring it, i tried to include it. It always fails with following:

ninja: build stopped: subcommand failedLooks likes a python issue? I see a 'ldd' at the bottom and that doesn't seem to work on my system. Eg. ldd /usr/bin/less yields "not a dynamic executable" - and same for libraries. Right now, I could live without introspection, except, I cant apply the elogind patch to polkit because when running autoreconf -fi after applying the patch IT complains about missing gir (grrr.)
