There's more going on. I added the libgtest-dev package, but the library is still not found. Looking at the Ubuntu package, the library is not part of libgtest-dev <http://packages.ubuntu.com/precise/amd64/libgtest-dev/filelist>. The only Ubuntu package containing the libgtest.so is ugene <http://packages.ubuntu.com/search?searchon=contents&keywords=libgtest.so&mode=exactfilename&suite=precise&arch=any>, which is not really what we're looking for.  So that leaves the question, where did we get install libgtest.so from in the past?
