This is a little issue I've encountered while installing the SLIC binary on a brand new SL5 CERN installation
It fails to run, because it doesn't have the right libstdc+. This is due SL5 having a gcc 4.x. The easiest way around is to install the libstdc+ compatibility rpm for gcc 3.x. (compat-libstdc++-33-3.2.3-61.i386.rpm) After this has been installed, it works fine
Similar fixes probably apply to a lot of other gcc 4 based systems
