[gentoo-user] glibc update 2.16 > 2.17 - python relocation error at end of emerge

[Tanstaafl]

I just updated glibc to 2.1.17, and got the following error at the very 
end of the emerge:

/usr/bin/python2.7: relocation error: /lib64/libresolv.so.2: symbol __sendmmsg, 
version GLIBC_PRIVATE not defined in file libc.so.6 with lin                    
                                   k time reference

Is this something to worry about?
