Failed to compile x86_64 version of php5

[ZelluX <zellux@xxxxxxxxx>]

Hi, all

I'm trying to compile php5 on dreamhost, after doing what http://wiki.dreamhost.com/index.php/Installing_PHP5 says, I have compiled all the components except php5 itself.

When running $ ./configure ${PHPFEATURES}, it reports an error 

configure: error: Cannot find libmysqlclient under /usr.
Note that the MySQL client library is not bundled anymore!

But actually I find that /usr/lib64/lib64/libmysqlclient.so.15.0.0 exists. After some googling I added a  --with-libdir=lib64 to the configure parameters. But this time another error appears

checking for pkg-config... /usr/bin/pkg-config
configure: error: Cannot find OpenSSL's li

I don't know how to make configure find both libraries. Many thanks for your replies.
