Using INSTALL_ROOT with make install not portable, other install questions

When using make INSTALL_ROOT=/var/tmp/root/php-5.3.17.0 install I get an error about httpd.conf not being in place for apxs (if I copy it ahead of time, apxs works fine) Isnt this to be expected - that httpd.conf is not avalibale, and apxs should just "fail" gently, leaving a warning but continuing? Not sure how to interpret this: what in install asking for, warning about? Installing PEAR environment: /var/tmp/root/php-5.3.17.0/opt/php/bin/ [PEAR] Archive_Tar - installed: 1.3.7 [PEAR] Console_Getopt - installed: 1.3.0 [PEAR] Structures_Graph- installed: 1.0.4 [PEAR] XML_Util - installed: 1.2.1 warning: pear/PEAR requires package "pear/Archive_Tar" (version >= 1.3.7) warning: pear/PEAR requires package "pear/Structures_Graph" (recommended version 1.0.4) warning: pear/PEAR requires package "pear/Console_Getopt" (recommended version 1.2.3) warning: pear/PEAR requires package "pear/XML_Util" (recommended version 1.2.1) [PEAR] PEAR - installed: 1.9.4 Wrote PEAR system config file at: /var/tmp/root/php-5.3.17.0//var/php/etc/pear.conf You may want to add: /opt/php/bin to your php.ini include_path /data/prj/php/php-5.3.17/build/shtool install -c ext/phar/phar.phar /var/tmp/root/php-5.3.17.0/opt/bin ln -s -f /opt/bin/phar.phar /var/tmp/root/php-5.3.17.0/opt/bin/phar Installing PDO headers: /var/tmp/root/php-5.3.17.0/opt/include/php/ext/pdo/ And, why it install already mentioning/touching (in this case /opt/* when all should be in $INSTALL_ROOT? Suggestions welcome, even if it just "what to say" in a bug report. Michael
