Hi Christof,

I am not sure if this could be the reason but libtool is extremely 
resilient when it comes to memorizing outdated libraries (in those *.la 
files in the install area). In the past we removed those files during 
the build but getting us ready for SL7 forced me to leave them.

If I see these kind of weird things I normally take the scorched earth 
approach - remove the install and build areas and start from scratch 
with running autogen. One can probably in each case find a less drastic 
way but that normally takes longer than just rebuilding from scratch.

Also if by any chance you are using an existing ana build somehow - that 
would be another way to get the root versions mixed.

Experimentally I found that this warning didn't matter for the result. 
When running tests - the results came out identical. It's not too 
surprising - the versions are very similar (handful of bugfixes) but one 
never knows

I hope that helps - if you still run into issues, let me know where your 
libraries are and I'll have a closer look,

Chris
