llvm dev - Jul 2011 - [LLVMdev] [compiler-rt] trunk fails ctest on X86_64 Linux

If this is not the proper place to report this problem, I apologize
and would like to know the proper avenue. Information on compiler-rt
is very scarce, and I have been unable to get block support on Linux
any other way.

I'm running X86_64 Ubuntu Linux, and I checked out the trunk of
compiler-rt and built it according to the instructions on it's page,
and ran the test suite. Three tests failed:

The following tests FAILED:
        24 - enable_execute_stack_test (SEGFAULT)
        38 - fixunssfti_test (Failed)
        74 - fixunsdfti_test (Failed)

The code built without any errors. Some warnings were output, all of
which are identical to this one, save the file in which it occurs
[ 90%] Building C object

/home/taylorh/prog/compiler-rt/test/Unit/powitf2_test.c:229: warning:

I am building with gcc 4.4.3-4ubuntu5, though I doubt that matters. I
have tried building with a release build of clang 2.9 (trunk 115910)
and the errors are identical.

The following lines of output seem relevant. They all come from the
following pastebin http://pastebin.com/YJDEr4bY

~~~~~headers not found during cmake~~~~~
~~~~~Note: Missing headers are of course a red flag, but I have been
unable to discover any way to get them. Google searches yield Apple
developer documentation, which isn't terribly helpful when I appear to
need the libraries to build something that allows blocks to function
on non-OS X systems~~~~~

If anybody can point me in the direction of getting compiler-rt to
build, I would be very grateful.
