Hi, I've been trying to rebuild a fedora 12 glibc 2.11.1 SRPM using mock for the 
x86_64 arch, but it always fails at:

DEBUG: + for i in '$RPM_BUILD_ROOT/usr/bin/{xtrace,memusage}'
DEBUG: + sed -e s~=/lib64/libpcprofile.so~=/usr/lib64/libpcprofile.so~ -e

's~='\''/\\\$LIB/libpcprofile.so~='\''/usr/\\$LIB/libpcprofile.so~' -e 
's~='\''/\\\$LIB/libmemusage.so~='\''/usr/\\$LIB/libmemusage.so~' -i 
/builddir/build/BUILDROOT/glibc-2.11.1-3.fc12.x86_64/usr/bin/memusage
DEBUG: sed: can't read /builddir/build/BUILDROOT/glibc-2.11.1-
3.fc12.x86_64/usr/bin/memusage: No such file or directory
DEBUG: error: Bad exit status from /var/tmp/rpm-tmp.ygMzgm (%install)

help?
