    If anybody stumbles across this from Google, I found that the simplest thing to do was:
Have devs install rbenv on their machines, and add ~/.rbenv/shims to the PATH in the XCode build script like:
export PATH=~/.rbenv/shims:$PATH
# Exec rest of your script
# ...


A slightly more complicated, but more customizable solution is to have your script start with the following:
XCODE_ENV=.xcode-env
XCODE_LOCAL_ENV=.xcode-env-local

# Setup your env variable overrides here
if [ -f $XCODE_LOCAL_ENV ]; then
    source $XCODE_LOCAL_ENV
fi

# Source default environment variables
source $XCODE_ENV

# Exec rest of your script
# ...

The .xcode-env file contains:
#
# Default XCode ENV
#

# Set RBENV_SHIMS if undefined
if [ -z $RBENV_SHIMS ]; then
    RBENV_SHIMS=~/.rbenv/shims
fi
export PATH=$RBENV_SHIMS:$PATH

So, if you want to specify alternative environment variables, you can create a .xcode-env-local (which is gitignored) with content like:
RBENV_SHIMS=/some/other/path/to/.rbenv/shims
