Kraken installation via tool shed on Mac OSX 10.10.5 (for development)

I get the following error installing the 'kraken' part of the devteam kraken tool from the tool shed:

```
In file included from krakendb.cpp:20:
./kraken_headers.hpp:36:10: fatal error: 'omp.h' file not found
#include
^
1 error generated.
make: *** [krakendb.o] Error 1
/bin/sh: /bin/true: No such file or directory
```

tool: devteam kraken 0.10.5

Start with the devteam kraken 0.10.5 build around krakendb.cpp and kraken_headers.hpp, then inspect the installation output for the missing omp.h and /bin/true errors on Mac OS X 10.10.5. Determine whether the tool can complete installation in that environment; done means the Kraken tool installs without these build failures.
