I'm trying to build FB15 on linux. When running autoconf (the very
first step in the build process), I get:

configure.in:143: error: possibly undefined macro: AC_PROG_LIBTOOL
If this token and others are legitimate, please use
m4_pattern_allow.
See the Autoconf documentation.
configure.in:144: error: possibly undefined macro: AC_LIBTOOL_DLOPEN
configure.in:145: error: possibly undefined macro:
AC_LIBTOOL_WIN32_DLL

I'm not quite sure what's going wrong, but suspect that my build tool
chain is too old/new. The versions I use are:

Libtool version = 1.5 (1.1220)
autoconf version = 2.58

Please advise. Thanks in advance.

PS I would prefer to fix the config files over changing the versions
of my build tools
