The oldest release of Slackware that I can build Trinity is 13.1. 
In bug report 1741 I shared my attempts at building Trinity in 
Slackware 12.2 and 13.0. Ignoring cmake, newer versions of several 
upstream packages need to be backported to build Trinity in 
Slackware 12.2 or 13.0. Trinity builds in Slackware 13.1 just fine. 
Slackware 13.1 was released with cmake 2.8.1.

If we establish cmake 2.8 as a minimum requirement, we then --- 
indirectly --- include other problematic upstream packages against 
which Trinity would not build. That is, any distro that came with 
cmake 2.8 likely did not include the older upstream packages that 
would be problematic for building Trinity.
