hmmm, the only thing that worries me about dynamic linking is that it will add variability to the outputs. Zeke has spent endless amounts of time tracking down e.g. mac vs. pc differences in math libs and such.
What sort of differences were found? Differences in transcendental functions are to be expected (so long as they are small) and lots of other things can cause slightly different results to be generated from floating point calculations (for instance, when summing an array, the result might vary with the number of OpenMP threads used). Were the segmentations produced intolerably different?
