yup does break if you try to use python2 to run it.
The solution I use is to have both python1.5.2 and python 2.2 installed
/bin/python is a sym link to either python1.5 or python2.2
cat <<EOF >/usr/bin/pythonsetver
#!/bin/sh
# script to set python to either version 1.5 or 2.2
cd /usr/bin
rm -rf /usr/bin/python
ln -s /usr/bin/python\$1 /usr/bin/python
ls -lah /usr/bin/python*
EOF
[root@localhost pac1]# chmod +x /usr/bin/pythonsetver
[root@localhost pac1]# /usr/bin/pythonsetver 1.5
lrwxrwxrwx 1 root root 18 Dec 12 19:17 /usr/bin/python ->
/usr/bin/python1.5
-rwxr-xr-x 1 root root 437k Sep 23 17:53 /usr/bin/python1.5
-rwxr-xr-x 1 root root 2.3M Dec 8 15:04 /usr/bin/python2.2
-rwxrwxr-x 1 root root 162 Dec 12 19:17 /usr/bin/pythonsetver
Then just yup to your heart's content.
When done,
just /usr/bin/pythonsetver 2.2
switch as needed.
[root@localhost pac1]# /usr/bin/pythonsetver 1.5
lrwxrwxrwx 1 root root 18 Dec 12 19:38 /usr/bin/python ->

[root@localhost pac1]# /usr/bin/pythonsetver 2.2
