Great.  Thanks for testing.  I'll include it in CMake upstream as
soon as we have finished transitioning to the new Git repository
I announced yesterday and open it for publishing.

The platform support files have been significantly refactored
in 2.8.1-rc[123] since 2.6.0.  Please port it to the new layout
and test it.  It will probably get simpler.

These two build executables and then modules (DLLs) that "link"
to the executables so that they use a plugin API at dlopen time.
Likely your platform file needs some flag tweaking.  Look at

  CMAKE_EXE_EXPORTS_C_FLAG

in Linux.cmake.

I guess this one will have to be debugged manually.

These do not affect use of CMake to build a project, but
do affect CTest.  I'd need to see output to debug them.

BTW, once we get this working will you be able to submit
a nightly dashboard entry so we can keep it working?

Thanks,
