Can't find libtool when configuring 1.2.0

[Steve Cayford <scayford terracom net>]

Hi. I'm trying to move up from Balsa 1.1.7 to 1.2.0, but when I run
configure I get this error:

checking for lt_dlopen in -lltdl... no
configure: error: *** libtool not found.  Please check http://www.balsa.net
for information on the required files.

and in the config.log I get:

configure:3250: checking for lt_dlopen in -lltdl
configure:3269: egcs -o conftest -g -O2  -I/usr/include/gtk-1.2
-I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/X11R6/include 
conftest.c -lltdl   1>&5
/lib/libdl.so.2: undefined reference to `_dl_vsym@GLIBC_2.2'
/lib/libdl.so.2: undefined reference to `_dl_sym@GLIBC_2.2'
collect2: ld returned 1 exit status
configure: failed program was:
#line 3258 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char lt_dlopen();

int main() {
lt_dlopen()
; return 0; }

A little confused about this. I just compiled libesmtp 0.8.4 fine, and
after getting this error I went back and re-configured and compiled balsa
1.1.7 just fine. Any hints?

Thanks.
