When compiling mozilla-firefox-2.0.0.1-r4, it crashes, complaining that it can't find libexpat.so.0. A recompile of the expat package did not solve the problem. I currently have the 2.0.0 expat package installed. Reproducible: Always Steps to Reproduce: 1. Upgrade to expat 2.0.0 2. Try to compile mozilla-firefox-2.0.0.1-r4 package 3. Fail /var/tmp/portage/www-client/mozilla-firefox-2.0.0.1-r4/work/mozilla/config/nsinstall -R -m 755 libxpcom_compat_c.so ../../../dist/bin/components ../../../dist/bin/elf-dynstr-gc ../../../dist/bin/components/libxpcom_compat_c.so ../../../dist/bin/elf-dynstr-gc: error while loading shared libraries: libexpat.so.0: cannot open shared object file: No such file or directory
You need to revdep-rebuild after upgrading to expat.
