I think it's a Mandrake 10 box.

There is a bit of a trick needed for CMake due to support for loaded 
commands.  We link statically against everything but libc and libdl.  In 
order to work with the system libc on every other machine you need to 
build with the oldest glibc you can find.  We used to use an old glibc 
2.0 system to build binaries but that old machine died so now we use a 
glibc 2.3 system.  A few years ago that may have been a problem but no 
one has complained yet about needing glibc 2.3.  For the few people that 
have such old systems they can build from source.
