I was updating dev-libs/glib from 2.6.2-r1 to 2.6.3 and adding use flags doc and hardened. I received the following error: *** Building HTML *** rm -rf ./html mkdir ./html cd ./html && gtkdoc-mkhtml glib ../glib-docs.sgml /usr/bin/xsltproc: error while loading shared libraries: libgpg-error.so.0: cannot open shared object file: No such file or directory locate libgpg-error showed only portage related stuff, dev-libs/gpg-error was not installed. After emerging libgpg-error, glib emerged OK. Reproducible: Always Steps to Reproduce: 1. Ensure dev-libs/libgpg-error is NOT installed (emerge -C dev-libs/libgpg-error) 2. USE="doc hardened" emerge =dev-libs/glib-2.6.3 3. Actual Results: *** Building HTML *** rm -rf ./html mkdir ./html cd ./html && gtkdoc-mkhtml glib ../glib-docs.sgml /usr/bin/xsltproc: error while loading shared libraries: libgpg-error.so.0: cannot open shared object file: No such file or directory Expected Results: If libgpg-error is needed to build glib, it should be a dependency. My guess is that the doc use flag for glib-2.6.3 needs libgpg-error.

no it doesn't .. you need to rebuild libgcrypt & maybe libxslt, libgpg-error is a dep when its needed. You either removed the pack yourself or the so versioning changed, but i doubt the latter.
