my_print_defaults: not found when making 1st sandbox (ubuntu)

Installed MySQL sandbox (using the README docs), also installed perl-doc. On ubuntu (lenny):
Linux myserver 2.6.24-19-server #1 SMP Wed Jun 18 14:44:47 UTC 2008 x86_64 GNU/Linux

command I ran:
  make_sandbox /home/me/mysql-5.1.36-linux-i686-glibc23.tar.gz

unpacking /home/dba/mysql-5.1.36-linux-i686-glibc23.tar.gz
Executing low_level_make_sandbox --basedir=/home/dba/5.1.36 \
 --sandbox_directory=msb_5_1_36 \

I answer Y to the parameters (they look ok)

Then I get:
/home/me/5.1.36/scripts/mysql_install_db: 244:
/home/me/5.1.36/bin/my_print_defaults: not found
error while creating grant tables
Neither host 'eval-db1-vm1' nor 'localhost' could be looked up with
/home/me/5.1.36/bin/resolveip
Please configure the 'hostname' command to return a correct
hostname.
If you want to solve this at a later stage, restart this script
with the --force option

If I go into the 5.1.36 dir I see the files in the bin dir. :
ls -l bin/my_print_defaults
-rwxr-xr-x 1 me 1035 1839908 2009-06-16 09:52 bin/my_print_defaults

./bin/my_print_defaults --help
-bash: ./bin/my_print_defaults: No such file or directory

So somehow I must have the wrong download for my system? I've only been installing 5.0.51a with Ubuntus package ... and I need to keep the default in place ...

thoughts? suggestions?

thanks,
erin
