Well I compiled PHP with the following ./configure options:
(I'm the only user on my system - 'keith' or 'root')

'./configure' \
'--with-apxs2=/usr/local/apache-2.2.6/bin/apxs' \
'--prefix=/usr/local/php-5.2.4' \
'--bindir=/usr/local/bin' \
'--enable-shared=all' \
'--with-pear=/usr/local/PEAR' \
'--with-mysql=shared,/usr/local/mysql-5.0.45' \
'--with-mysql-sock=/var/lib/databases/mysql/mysql.sock' \
'--with-mysqli=shared,/usr/local/mysql-5.0.45/bin/mysql_config' \
'--with-pgsql=/usr/local/postgresql-8.2.5/bin' \
'--with-xsl' \
'--with-zlib-dir=/usr/include' \
'--with-readline' \

Subsequent PHP compilations use:

'./configure' \
'--with-apxs2=/usr/local/apache-2.2.6/bin/apxs' \
'--prefix=/usr/local/php-5.2.4' \
'--bindir=/usr/local/bin' \
'--enable-shared=all' \

'--without-pear' \

'--with-mysql=shared,/usr/local/mysql-5.0.45' \
'--with-mysql-sock=/var/lib/databases/mysql/mysql.sock' \
'--with-mysqli=shared,/usr/local/mysql-5.0.45/bin/mysql_config' \
'--with-pgsql=/usr/local/postgresql-8.2.5/bin' \
'--with-xsl' \
'--with-zlib-dir=/usr/include' \
'--with-readline' \

So I now have PEAR in /usr/local/PEAR. Reason for doing this 
is to preserve the PEAR installation between OS upgrades. 
/usr/local is on a seperate partition. I have not had any 
problems with PEAR or the applications it provides not 
functioning correctly so far.

I generally run PEAR as root user anyway, so maybe that's 
why I have not encountered the /tmp/pear/cache writeable 
problem you mention. What about creating a seperate group 
for the /tmp/pear/cache, and adding your normal users to it, 
so they have write access to that dir?

Here is the output from pear config-show:

It seems that any modifications to PEAR's configuration 
using 'pear config-set' are written to the User 
Configuration File, not the System Configuration File. I 
must have installed PEAR as root user, because that is where 
the .pearrc file is located in.
