It described an executable file named "mongo" under a bin directory.

Okay so I see that they are in my filesystem and they don't look very strange.

I did some google searches and found an interesting document:

According to the above document, and the above otool output, it seems plausible that bin/mongo is looking for the libboost_*.dylib files in the bin/ directory.
One worrisome aspect of the above output is that the libboost-lines display version strings which contain only zeros.

Anyway,
according to the above document, and the above otool output, it seems plausible that bin/mongo is looking for the libboost_*.dylib files in the bin/ directory.

At this point I felt that installing MongoDB from source on my Mac was too much effort.

I was ready to knuckle under and use Homebrew.
