this means a test piece of code, generated by configure, with a call to 
mysql_close() failed. It does not neccessarily mean that there is no 
mysql_close() in libmysqlclient. You need to run by hand the piece of code and 
see why it failed. It's possible that some other dependency is not satisfied.

You can find the piece of test code with

sh -x configure --prefix=/usr .... > foo.out 2>&1

and spelunk the output for mysql_close()

assuming this is true, it is most likely that you'll have to recursively 
download the internet and compile it (and install binaries) to satisfy the 
dependencies. You will eventually get to a spot that you can't compile, no 
matter what and you'll find that a lot of your currently working packages no 
longer work anymore. I would suggest taking an image of your setup first in case 
this happens. Over the last 20yrs of Linux, I've found that once your distro is 
too old, it cannot be upgraded anymore. You have to start with a fresh version 
of the distro and start as if from a new install. Do you really need the new php 
on this machine that badly?
