UNIX for Advanced & Expert Users

I faced the following error while configuring the spine for cacti. Can any one help me to sort out this problem:

hecking how to run the C++ preprocessor... g++ -E
checking for g77... g77
checking whether we are using the GNU Fortran 77 compiler... yes
checking whether g77 accepts -g... yes
checking the maximum length of command line arguments... 32768
checking command to parse /usr/bin/nm -B output from gcc object... ok
checking for objdir... .libs
checking for ar... ar
checking for ranlib... ranlib
checking for strip... strip
checking for correct ltmain.sh version... no
configure: error:

*** [Gentoo] sanity check failed! ***
*** libtool.m4 and ltmain.sh have a version mismatch! ***
*** (libtool.m4 = 1.5.22, ltmain.sh = 1.5.6) ***

Please run:

libtoolize --copy --force

if appropriate, please contact the maintainer of this
package (or your distribution) for help.

Have you looked into upgrading whichever package provides ltmain.sh, or downgrading libtool, or running libtoolize --copy --force like the error message suggests?
