problems with Engelschall upgrade toolkit

[Charlie McElfresh]

Hi,

I'm running Ralf Engelschall's upgrade toolkit, in an effort to get
from 5.4release to 6.

I did

make upgrade

and when I try to run

make etc

I come to this prompt

How should I deal with this? [Use the existing /var/tmp/temproot]

I hit "enter", and I get this error message:

  *** FATAL ERROR: Cannot 'cd' to /usr/src/etc and install files to
      the temproot environment

*** Error code 1

Stop in /usr/adm.
*** Error code 1 (ignored)

Help appreciated.
