Replying to this on-list just incase other people have this problem. Not sure if I ever submit this patch back to the list, but I added support for backtraces so you can see the function call stack for traced functions.
The problem with this feature is that I didn't take the time to fix the configure script so that it would disable that code if you don't have libunwind on your system. There are two solutions: 1.) The simplest solution (until I or some one else fixes the configure script) is to install libunwind library and header files on your system and try building my branch again. or 2.) Rewind the source tree in git to before that commit was made. To do this you can just: git checkout a95f1 -b before_unwind That will create a local branch called "before_unwind" (the first byte of the sha before the libunwind commit are a95f1). The downside is that if you do this you lose some of the man page cleanup and a small bugfix.
