The problem is that an upgrade from so.0 to so.1 breaks so many things that it
necesitate a near total recompile... and lost time etc. while the .so.1 gets linked back in again :(
Steps to Reproduce:
1.have a system with libexpat.so.0
2.esync && emerge -uDN system
problems with gettext, gnome packages (xulrunner, XPCOM), kde/qt, apache2, PHP, etc. etc. etc. etc.breaking until everything have been recompiled.
At least bug #189126 is related to this.
System continues working while the rest gets rebuild to fix this new version issue.
No, we are not going to slot this, already said many times.
