cassandragem on Mac OS X 10.9.5. The solution was a multipart solution. You first need to build
thriftfirst which has a known issue, and then build
cassandra. This technical tip is very simple. I didn't want to lose it, and I am sure that there are other people out there who will need it.
Note: Please make sure you have updated all the gems in your repository before executing these commands. This will build both required gems.
