ecjtu

在redhat 9.0  gnome下,安装一个管理工具gentoo-0.11.23.tar.gz,解压后

configure: error: Bad GTK+ version
[root@localhost gentoo-0.11.23]# make
make: *** No targets specified and no makefile found.  Stop.
[root@localhost gentoo-0.11.23]# make install
make: *** No rule to make target `install'.  Stop.
但是我查看了一下gtk+,发现我已经装了,而且还是gtk+-1.2.10-25的,它上面好像是说要自己选择gtk+的路径
但是如何选择呢?
