PROSAGA码农传奇-memcache-配置：错误：C编译器无法创建可执行文件

我已经检查了许多关于stackoverflow的类似问题，但是还没有找到答案。我正在尝试在Lion OSX上安装memcached，如下所示。这就是我得到的：
<pre><code>j-court-demones-macbook-pro:libevent-1.4.12-stable jcourtdemone$ ./configure; make
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... no
checking for mawk... no
checking for nawk... no
checking for awk... awk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... 
configure: error: in `/tmp/libevent-1.4.12-stable':
configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** No targets specified and no makefile found. Stop.
</code></pre>我已经按照几个地方的建议重新安装了Xcode，但是没有骰子。这是我的config.log：
<pre><code>This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.63.  Invocation command line was

$ ./configure
