mock problems

[Josh Boyer]

Anyone know what the following means:

Errors cleaning out chroot: mock-helper: error: /var/lib/mock//fedora-development-i386-core: No such file or directory
Starting Prep
Preparing Root
making /dev devices
making misc files of use
making yum.conf
yum: command /usr/sbin/mock-helper yum --installroot /var/lib/mock//fedora-development-i386-core/root groupinstall build
Creating user for builds
Closed
Non-zero return value 127 on executing /usr/sbin/mock-helper chroot /var/lib/mock//fedora-development-i386-core/root /sbin/runuser - root -c "/usr/sbin/useradd -u 500 -d /builddir mockbuild"

I've added myself to the mock group, and I'm using mock-0.3-2.fc4.  I'm
probably forgetting a step somewhere...
