I am an ardent practitioner of the Six Stages of Debugging. One is forced to, when one's software needs to simultaneously work on Mac OSX and RHEL5 Linux and modern Linux (these two are, in fact, very different). Until the cows actually come home and the day of the Linux desktop is here, I have to continue contending with OSX and its eccentric ways.
One of which is how OSX handles run-time search paths for shared libraries that
you build yourself. CMake luckily has a great explanation of rpath
differences in Linux and Macs. It's a beautiful default behavior until Linux
screams at me with SYMBOL LOOKUP ERROR GOODBYE while everything seemingly
chugs along in OSX. I'm assuming this is because nobody cares about Unix
portability at Apple. In any case, for these situations
probably the easiest thing to do without modifying other people's
LD_LIBRARY_PATH or system libs.
