Revision 4
Comment: I am trying to get this wiki to work for me, but my Xcode 3.2 on a SL machine has exactly the same libgcc_s.10.5.dylib as the Leopard 3.1 Xcode!  The information needs to include better details of the required libgcc and what exact systems might have it, or where it can be obtained from (or patch file).  These changes are intended to help more novice users proceed with maintaining their installed macports ports and dependencies with the updates.  I have just upgraded the SL machine to Lion & installed the oldest Xcode for it (4.1), but I still can't find the required libgcc_s10.5.dylib - I don't know which newer version this wiki is referring to or where to find it.  Do I need to do something special in Xcode 4.1 to populate it?
