Installation script doesn't check for location before testing with md5sum

[GoogleCodeExporter]

Following the steps from the wiki on a stock Debian Squeeze:

svn checkout https://fusionpbx.googlecode.com/svn/trunk/scripts/install/ubuntu/ 
/usr/src/install_fusionpbx
chmod 755 /usr/src/install_fusionpbx/install_fusionpbx.sh
ln -s /usr/src/install_fusionpbx/install_fusionpbx.sh /usr/local/bin/
sudo /usr/local/bin/install_fusionpbx.sh install-both user |tee 
/tmp/install_fusion.log

The installer complains of the md5sum of the latest script doesn't match, and 
offers to abort as per: 
<snip>
Codename:       squeeze
Do you want to continue [y|n]? y
Ok, this doesn't always work..,
  but we'll give it a go.

md5sum: /root/install_fusionpbx.sh: No such file or directory
The md5sum of the current script is:
The md5sum of the latest script is: 0aba4a8ff20b7de81c9db6ca226659e6
There is a new version of this script.
  It is PROBABLY a good idea use the new version
  the new file is saved in /tmp/install_fusionpbx.latest
  to see the difference, run:
  diff -y /tmp/install_fusionpbx.latest /root/install_fusionpbx.sh
Continue [y/N]? ^C

The location /root/install_fusionpbx.sh appears to be hard coded; a manual

It is not hard coded, but I agree it does not always work as expected.  To the 
best of my knowledge there is not a sure fire way to get the exact path to a 
script that's running (from inside the script itself).  Here's how I've taken 
the approach:

#Check for new version
WHEREAMI=$(echo "`pwd`/`basename $0`")
wget $URLSCRIPT -O /tmp/install_fusionpbx.latest
CURMD5=$(md5sum "$WHEREAMI" | sed -e "s/\ .*//")
echo "The md5sum of the current script is: $CURMD5"

If you know of a better way, I'd appreciate the knowledge.
