sbuild binary cannot be found inside schroot

While learning how to build packages, following the guide here:

https://help.ubuntu.com/community/SbuildLVMHowto

It seems sbuild cannot be found inside my schroot, see below. It looks like that this maybe was left out of the initial root image creation?
