homebrew - brew install php55出现问题

执行

brew install php55

的时候有这这一堆：

Warning: Backing up all known pear.conf and .pearrc files
Warning: If you have a pre-existing pear install outside
     of homebrew-php, or you are using a non-standard
     pear.conf location, installation may fail.

然后：

./configure --prefix=/usr/local/Cellar/php55/5.5.21 --        localstatedir=/usr/loca
checking for krb5-config... /usr/bin/krb5-config
checking for DSA_get_default_method in -lssl... no
checking for X509_free in -lcrypto... yes
checking for pkg-config... no
configure: error: Cannot find OpenSSL's

显示的是我之前安装的版本和安装时间。那么另一个问题就来了，如何完全清理brew 安装的php？
