whilst trying to install the latest 6.1.0.4 fixpack onto an installation of WebSphere Portal Server / Lotus Web Content Management 6.1.0.3. I'd previously seen the same exception last week, on another VM, but hadn't had a chance to dig into it further.

Sadly, I'd seen the messages but hadn't really read the messages :-)

When I read into it more fully, the significance of "the specified product version is not supported: version=6.1.0.27" became more relevant; WebSphere Portal 6.1.0.3 ships with, and installs by default, WebSphere Application Server 6.1.0.27, whereas 6.1.0.4 requires WebSphere Application Server 6.1.0.29, as per: -

WebSphere Portal Express V6.1.0.4 and V6.1.5.1 hardware and software requirements - Linux on x86

http://www-01.ibm.com/support/docview.wss?uid=swg27018305

Once I installed the .29 fixpacks: -

6.1.0-WS-WAS-LinuxX32-FP0000029.pak
6.1.0-WS-WASSDK-LinuxX32-FP0000029.pak

I was able to successfully install the 6.1.0.4 fixpack.

Can you say "Muppet" ? I bet you can ......
