I am trying to install a copy of PHP 5 to my home directory on the school computer. The problem is that whenever I try, it complains that my copy of libxml2 is too outdated to work.
Is there any way I can install this without upgrading libxml2, since I don't have permission to upgrade.
Any suggestions?
Answer
Alternatively, you can make an install of libxml in your home directory and pass configure the location where you've installed it, i.e.
--with-libxml-dir=<your local install>
When installing libxml, you just have to use the --prefix= option with configure to indicate that you don't want to do a system install.
Assuming that you compiled the cli client (and that the lib search path for the current user and the apache user are the same), you check that the correct lib is linked with:

libxml is listed half-way down the library list.
