after 3.62 install, configuration check fails - 'suexec command was not found on your system'

On upgrading to Virtualmin Pro v 3.62, the configuration check must be run. It fails with the message:

'Suexec is enabled in the default template, but the suexec command was not found on your system.'

Nothing has changed with the apache setup, and
root@vps02:/var/log/apache2# /usr/lib/apache2/suexec2 -V
-D AP_DOC_ROOT="/home"
-D AP_GID_MIN=100
-D AP_HTTPD_USER="www-data"
-D AP_LOG_EXEC="/var/log/apache2/suexec.log"
-D AP_SAFE_PATH="/usr/local/bin:/usr/bin:/bin"
-D AP_UID_MIN=100
-D AP_USERDIR_SUFFIX="public_html"
root@vps02:/var/log/apache2#

So it appears to be present.
