Compile-time error with numba 0.11.0: "np_datetime.o: requires dynamic R_X86_64_PC32 reloc...'

Hi guys,

I'm having trouble compiling numba 0.11.0 from source. While executing python setup.py build_ext --inplace I hit this linker error:

I'm running Ubuntu 13.04 (3.8.0-31-generic) and using Python 2.4.7 and GCC 4.8.1. I compiled LLVM 3.3 from source in a temporary directory, using REQUIRES_RTTI=1.

I am trying to install numba in a clean virtualenv with no system site packages, containing:

• Cython==0.19.2
• argparse==1.2.1
• cffi==0.7.2
• distribute==0.6.34
• ipython==1.1.0
• llvmmath==0.1.1
• llvmpy==0.12.0-55-g18d3b48
• nose==1.3.0
• numpy==1.9.0.dev-84c52d8
• pycparser==2.10
• wsgiref==0.1.2

Both llvmpy and llvmmath seem to be installed properly and working fine - they pass all of their respective nose tests. There's a single failure with numpy somewhere in test_io, nothing that looks critically important.

What's more, using the same virtualenv I am able to build and install numba 0.10.2 successfully, and it passes almost all of its nose tests (I get two failures, one in test_datetime and one in test_nosource.

Any ideas where the problem might lie?

Haha, spent ages working on a bug report, then I manage to post it on the wrong repo. This was meant for the numba guys, please totally ignore it. I should probably sleep now...
