This is probably a trivial question, but I have the GNU coreutils installed, along with many Python packages and some other things. I was expecting that I may have to re-compile or re-install some/all of these things since OS X 10.8 / Xcode 4.4 has a newer version of GCC, etc. However, everything seems to work fine so far. Should I recompile everything anyway? Am I risking some bug down the line? Or since the programs run fine, should everything be alright? I don't fully understand how exactly this works post-compile.
Edit: Both Coreutils and Python were built from source, then Python packages were installed with
pip or the equivalent. Everything seems to work fine, I'm just a bit paranoid.
