The oldest version I was able to find online was
http://www.dealii.org/download/deal.II-6.0.0.tar.gz

All that I get trying to build it is a warning from the linker saying

ld: warning: direct access in <sym1>  to global weak symbol <a vtable>
means the weak symbol cannot be overridden at runtime. This was likely
caused by different translation units being compiled with different
visibility settings.

Which is benign since the vtable doesn't need to be overridden at
runtime. I am using ld64-128.2, which version do you have?

Cheers,
Rafael
