This variable is used to tell the dynamic loader to use a glibc with 
LinuxThreads. See http://people.redhat.com/drepper/assumekernel.html for 
more information.

Since the SL5 kernel does not support LinuxThreads, there's also no such 
glibc provided. Hence software that relies on the specifics of 
LinuxThreads, and doesn't work with NPTL, can't be used on SL5.

I'm afraid no. In the past we could fix some problems by replacing the 
ancient JVMs coming with some commercial applications. But this seems to 
affect the (maple) kernel itself. I think not even Maple 8 will work on 
SL5.

If you find a way to get old versions of maple going on Sl5, please let me 
know...

Cheers,
