how to compile php with new ini setting? - trying to use aspell with php

[Notgiven]

I need to add aspell capability to php. I added the following line:

extension=libas pell.so

The extension directory is:
extension_dir = /usr/local/apache2/libexec/modules

and I put the aspell cirectories under that like so the extension is
actually:

/usr/local/apache/libexec/modules/aspell/lib/libaspell.so

I thought that would do it. But when I run php_info() it does not display
in the Configure Command that it is "--with-aspell". SO I am missing
something.

I was not able to compile aspell so I found a precompiled version and put it
under the extension_dir.

Any ideas? Many thanks!!
