Provide an AUTOMAKE_VERSION environment variable

在OpenBSD 5.0-current上编译libfaac的时候出现如下问题

[root@cactus /usr/src/faac-1.28]# ./bootstrap
Provide an AUTOMAKE_VERSION environment variable, please
Provide an AUTOCONF_VERSION environment variable, please
Provide an AUTOMAKE_VERSION environment variable, please
Provide an AUTOCONF_VERSION environment variable, please

检查一下automake和autoconf的版本：

[root@cactus /usr/src/faac-1.28]# pkg_info | grep auto
autoconf-2.59p3     automatically configure source code on many Un*x platforms
autoconf-2.68       automatically configure source code on many Un*x platforms
automake-1.9.6p8    GNU standards-compliant Makefile generator
metaauto-1.0        wrapper for gnu auto*

设置相应的变量：

[root@cactus /usr/src/faac-1.28]# export AUTOMAKE_VERSION=1.9  （=1.9.6不行）
[root@cactus /usr/src/faac-1.28]# export AUTOCONF_VERSION=2.68
[root@cactus /usr/src/faac-1.28]# ./bootstrap
