Hi,

I don't use RHEL, but I guess the problem is that IDL was compiled against
a different standard C++ library. On SuSE 9.0, this problem is solved by a
'compatibility' RPM, which contains different versions of the standard C++
library. Probably RHEL has something similar. As a dirty trick, you can
try

ln -s /usr/lib/libstdc++.so.5 /usr/lib/libstdc++-libc6.2-2.so.3

regards,
lajos
