请教：安装软件出错，怎么解决。

[viger]

我是新装的ubuntu7.01 服务器版，在自己本机上（XP SP2）用WMWARE虚拟的系统。
我想编译安装一个从网上自己DOWN下来的lrzsz-0.12.20包。
以下是出错信息：
viger@v-lamp-serv:/usr/local/lrzsz$ sudo ../../lrzsz-0.12.20/configure
loading cache ./config.cache
checking for a BSD compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking whether make sets ${MAKE}... yes
checking for working aclocal... found
checking for working autoconf... found
checking for working automake... found
checking for working autoheader... found
checking for working makeinfo... missing
checking for gcc... gcc
checking whether the C compiler (gcc ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.

在此之前出现过检查都没通过的提示，然后我一一对应的安装了相应的软件，在装texinfo时候，没有异样，但是这里还是：checking for working makeinfo... missing
viger@v-lamp-serv:/var/deb$ info --version

可能存在的问题是我没有装上G++，不敢确定。
请论坛的朋友们帮我指出出错的地方，十分感谢！
