when installing php, it would be nice if configure could generate a little shell script with the config options specified, to make upgrading to new versions simpler. I use this:

--8<--

[mini:root]:/usr/local/src/php # cat makeline.sh 
#!/bin/sh

configopts='
        --enable-dbg=shared
        --with-dbg-profiler
        --with-gd=/usr/local/
        --with-imap
        --with-mysql=/usr/local
        --with-pgsql=/usr/local/pgsql
        --with-versioning
'

./configure $configopts \
        --with-apxs=/usr/local/apache/bin/apxs \
&& 
make all install 2>&1 | tee make.log

if [ -f config.cache ]; then rm config.cache; fi

apachectl stop
sleep 2
apachectl start

## now make the cgi binary

rm config.cache

./configure $configopts \
&&
make all install 2>&1 | tee -a make.log

--8<--

so all I have to do to upgrade is untar, copy that script in and run it. maybe configure could generate something more intelligent?
