I believe Large files are supported only with 2.4 kernels and certain
glibcs. Which basically means for proper large file support, you will
need Red Hat 7.1. Even then, some utilities don't work, Perl being
one. It is my understanding that USE_LARGE_FILES breaks binary
compatibility, so if you recompile perl, be aware some modules may
have issues unless you recompile them as well.
