Re: [Gems-users] Fwd: ruby/opal "version 'GCC_4.2.0' not found" error

[Greg Byrd <gbyrd@xxxxxxxx>]

Since you compiled correctly, I suspect this has to do with 
dynamic libraries.  Try setting the LD_LIBRARY_PATH 
environment variable to point to the same libraries you used 
during the compilation step.
You need to look for stdc++ and gcc_s libraries that do not 
include the "4.2.0" symbol.  Use the "strings" command to 
check.  For example, this is the library that's built with 
the 3.4.6 release of gcc:
% strings libgcc_s.so.1 | grep GCC
GCC_3.0
GCC_3.3
GCC_3.3.1
GCC_3.4
GCC_3.4.2
%

As long as you don't see "GCC_4.2.0", it should work.
