Once again, portage is unhappy and complains about this command
tunix calibre # g++ -O2 -march=native -pipe -fPIC -O2 -march=native -pipe -pthread -I/usr/include/python2.7 -I/usr/include -I/usr/include/podofo -c /var/tmp/portage/app-text/calibre-0.9.6/work/calibre/src/calibre/utils/podofo/output.cpp -o /var/tmp/portage/app-text/calibre-0.9.6/work/calibre/build/objects/podofo/output.o

compilation terminated.
The reason is a broken symlink
