[CALUG] libreoffice on F16 on vbox error

[How7]

Hi
I think I have used libreoffice calc on this install but not positive.
When I went to use it today I get these error messages in xterm:

~>  libreoffice
/usr/lib64/libreoffice/program/soffice.bin: relocation error: 
/usr/lib64/libreoffice/basis3.4/program/libvclplug_genlx.so: symbol 
__fdelt_chk, version GLIBC_2.15 not defined in file libc.so.6 with link 
time reference

What do I need to do?
