Libtool version mismatch error


i have installed gnuradio-3.1.3 from the tar ball and my distribution is
fedora 8.0.
I have been running several files in the gnuradio successfully. but now
while i was
trying to run the make command, i came to the following error.

…/…/libtool: line 463: CDPATH: command not found
…/…/libtool: line 1141: func_opt_split: command not found
libtool: Version mismatch error. This is libtool 2.2.4, but the
libtool: definition of this LT_INIT comes from an older release.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.4
libtool: and run autoconf again.
