What error do you get? Are you refering to the 'gethostbyname'
warning? You can ignore it. It shouldn't affect your run.

If you really want to get rid of it - you would have to edit
PETSC_ARCH/include/petscconf.h [after configure is run] - and remove
the lines related to PETSC_USE_SOCKET_VIEWER

And then rebuild the libraries.

You need an additional option 'LIBS=-lstdc++'
