Could not load libiconv.so.2, no such library ...   spacer
  You are working on a program which from time to time you recompile to see the result of your efforts. You may have done some upgrading or reinstallation of other packages for whatever reason and suddenly the compiled program does no longer start! The message displayed goes along the tune: 
Could not load libiconv.so.2, no such library ...
You are taken by surprise but don't worry ...
How it was solved   spacer
  ... a call to ldconfig usually puts the thing again in order. Don't forget that ldconfig requires root authorisation and that the command resides in /sbin directory. Consider that the system may for some good reasons have unloaded a library or due to prior installation changes the library has been withdrawn from the list of loadable libraries.
just a reminder ...
