Build of cpyrit on Mac OS X

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build and install any version of pyrit 0.2.4 and 0.2.5 were tested
2. Attempt to build cpyrit_CUDA 0.2.4 or 0.2.5 and the error attached will
appear

What is the expected output? What do you see instead?
Expect things to compile fine to install

What version of the product are you using? On what operating system?
Mac OS 10.5.8
Tried pyrit and cpyrit 0.2.4 and 0.2.5

Please provide any additional information below.
I have attached a screenshot of the output.

setup.py does not make any assumptions about where it should find 
libcuda.dylib. You
may symlink /usr/local/cuda/lib/libcuda.dylib to /usr/lib/libcuda.dylib like 
this:

ln -s /usr/local/cuda/lib/libcuda.dylib /usr/lib/libcuda.dylib

Running into a new problem, when I try to build the cpyrit module I get this:

The warning can be ignored

I tried that and installed the module, then ran pyrit list_cores and it only 
listed
my CPU cores, no GPU cores

Also after installing the module I tried this from the Troubleshooting guide:

Traes-MacBook:cpyrit_cuda trobrock$ python -c 'from _cpyrit import _cpyrit_cuda'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name _cpyrit_cuda

_cpyrit_cuda is part of the package 'cpyrit' so it should read

python -c 'from cpyrit import _cpyrit_cuda'

Now getting this:

Traes-MacBook:~ trobrock$ python -c 'from cpyrit import _cpyrit_cuda'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: CUDA seems to be unavailable or no device reported.

Guess this would be an issue with my CUDA install on my MacBook correct?

yes it is. Try compiling & running the examples from the SDK

Instead of the symlink for libcuda.dylib, you can also pass a search path to 
the build script:

stewreo$ LDFLAGS=-L/usr/local/cuda/lib python setup.py build
