I believe that "v2Release" targets the 3.5 framework (is that the same
as CLRv2?), but someone can correct me if I am wrong.

I'm currently running a previous version of IronRuby built for
"v2Release", so perhaps there is at least a patch that we can apply
(will a simple cast be sufficient?).

I'm trying to build the latest versions of IronRuby and IronPython for
inclusion into the next version of Ubuntu. The versions built on
dlr-0.9 were just removed. However, I must admit that I don't know if
people will really need v2Releases... I just thought I'd build them if
I could.
