Hmmm - it looks for a symbol that is no longer available in that version... 
From the error and your statement I guess that your app is linked against a 
3rd party library or an internal piece of code that you did not recompile, 
correct? 

If you can't recomipile the code you probably will not be happy. If you are 
trying to access symbols that were exported but aren't any longer and stuff 
like that you might be ok with exporting LD_ASSUME_KERNEL=2.2.5 but that will 
in your case most likely just change the error, not get rid of it. Especially 
c_type_b... The other thing you can try is install a 6.2 compat glibc. Since 
6.2 is so old, its not even part of the distribution anymore, but you can 
usually get away loading an older glibc-compat (i.e. I loaded the 
compat-glibc-6.2-2.1.3.2.i386.rpm from RH7.3 on a Fedora Core 1 box)... 

Either way, it comes down to your application simply being too old - try get 
an upgrade to whatever lib holds you back...
