libtool version number

[David Harvey]

In README.HG it says I need to have the following installed:

* autoconf-2.59
* automake-1.8.4
* libtool-1.5.24

which I do. But when I .bootstrap and configure and make I get:

/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. - 
D__GMP_WITHIN_GMP -I.. -DOPERATION_`echo mp_bases | sed 's/_$//'`    - 
O2 -pedantic -m64 -mtune=k8 -march=k8 -c -o mp_bases.lo mp_bases.c
../libtool: line 460: CDPATH: command not found
../libtool: line 460: CDPATH: command not found
../libtool: line 1138: func_opt_split: command not found
libtool: Version mismatch error.  This is libtool 2.2.6b, but the
libtool: definition of this LT_INIT comes from an older release.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.6b
libtool: and run autoconf again.
../libtool: line 1138: func_opt_split: command not found

Have the version numbers changed? Does README.HG need to be updated?  
Or am I doing something else wrong?

thanks
