I've installed TWiki 02 Sept 2004 on AIX 5.2. It just worked with no special work-arounds -- just a few oddities like diff's path: /usr/linux/bin. Most of the open source utils get installed to /usr/opt/freeware/bin, with links to /usr/bin.

I initially tried the Bull AIX Freeware versions of some of the pre-reqs, but I had trouble with Apache (sorry, I don't recall the exact problem). I ended up using RPMs from IBM. I already had PERL 5.8.0. I needed Apache 1.3.31, expat 1.95.7, rcs 5.7.2, and diffutils 2.8.1.

I've successfully upgraded to 4.0.1 with only a few missteps on the way. The upgrade script failed to upgrade a couple of .css files. That made pages look really ugly, particularly tables-of-contents, which were unreadable. There were also a handful of topics that gave me an RCS error if I try to edit them. I think this is the same as the problem described in DakarReleaseUpgradeGuide. I manually edited the ,v files to change what appears to be an owner field (was "root", now it's "nobody").

I've upgraded to TWiki 4.2 on AIX 5.3. It was mostly uneventful. Between my last TWiki upgrade and this one, both the hardware and the OS were replaced, and search hadn't been working properly. The TWiki upgrade motivated me to finally figure it out. I was using the AIX versions of egrep and fgrep, which do not work properly with TWiki. I installed the GNU versions, changed my SafeEnvPath to point to them, and all is well.
