Build Fail on Linker Error

Linker fails with following message:
```
duplicate symbol _verbosity in:
    build/temp.macosx-10.7-intel-2.7/lib/svm_common.o
    build/temp.macosx-10.7-intel-2.7/lib/svm_hideo.o
ld: 1 duplicate symbol for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang' failed with exit status 1
```
Both files had `_verbosity`, when only one should have.
