Hello,
if you are missing fixdist in AIX 5.1/5.2 try this perl script: [url]http://tranq.dorms.spbu.ru/aix/aix-get[/url]
This script allows you automatically check for updated AIX packages and rpms and download them. Please be sure to have enough free space in /usr/sys/inst.images or your custom download directorys provided by -d flag or -r (for rpms).

Usage example:
# aix-get -h (for help)
# aix-get -R -k -d /usr/sys/inst.images/update -r /usr/sys/inst.images/testrpms -P [url]http://myproxy.mycompany.com:3128[/url]

Prerequisites are:
wget*.rpm
You can either install it from 'AIX Toolbox for Linux Applications' CD or
dowload it from official toolbox page located at
[url]http://www-1.ibm.com/servers/aix/products/aixos/linux/rpmgroups.html#Applications/Internet[/url]

lynx-ssl*.rpm
This program (version with SSL support) is required if you want to have
LatestFixData file downloaded automatically. You can install it from
'AIX Toolbox Cryptographic Content' ( i.e. lynx-2.8.4-1ssl.aix4.3.ppc.rpm )
or download it from [url]http://www6.software.ibm.com/dl/aixtbx/aixtbx-p[/url]
If you have any reasons not to install lynx-ssl then you should provide
this file to aix-get manually.

The script is under the GNU General Public License (GPL), so please send your improvements and suggestions to the author Konstantin Starodubtsev. You will find his email adress in the header of the script.

Best regards
Tomas Baublys
