brasero-2.32.0 in the gnome overlay fails with the following error: * preserve_old_lib_notify() must be called from pkg_postinst() only * ERROR: app-cdr/brasero-2.32.0 failed: * Invalid preserve_old_lib_notify() usage Seems pretty easy to fix. It's not entirely clear why the old library should be preserved explicitly. How many packages depend on it, and would break when the libraries upgrade? At the very least, it should probably have a comment saying why it needs special treatment...
Hmmm, seems I answered my own question, it looks like when brasero builds, all the other brasero plugins build off the *existing* libbrasero-burn.so.0 system library, rather than the one it builds in it's own directory. A double compile, or uninstall of brasero first seems to cure it, but this might want an upstream bug. It seems a very odd way to build a library with plugins...
Fixed in overlay. Thanks for reporting.
