reclassified

I have the same problem. The PEAR install is ignoring INSTALL_ROOT and trying to install things directly into /usr/share/pear:

(...)
Installing PEAR environment:      /home/andreas/svn/BUILDROOT/usr/share/pear/
make[1]: Entering directory `/home/andreas/svn/php4/BUILD/php4-200209250900/build-apache'

Warning: mkdir(/usr/share/pear/.registry) [http://www.php.net/function.mkdir]: Permission denied in /home/andreas/svn/php4/BUILD/php4-200209250900/pear/System.php on line 236

Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-latest.zip

Snapshot 200211101739 Does NOT Work For Me(TM).

A "make install INSTALL_ROOT=/var/tmp/php-root" as it used
to work with php-4.2.x, end in:

Installing PHP SAPI module
Installing shared extensions:     /var/tmp/php-root/usr/lib/php4/
Installing PHP CLI binary:        /var/tmp/php-root/usr/bin/

cp: cannot stat `pear/scripts/phpextdist': No such file or directory

So we've got two problems:
o  INSTALL_ROOT is still not honored.
o  There's a new problem with phpextdist.

I'm not sure if this is related, but I also have a problem with the PEAR installation of php (with php4-STABLE-200211121630):

libtool: install: warning: remember to run `libtool --finish /usr/src/php4-STABLE-200211121630/libs'

There have been some fixes in CVS related to this.
Please try the CVS HEAD (or the latest snapshot).
If you try with snapshot, make sure the pear/install-pear.php has the /* $Id... line in the top.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

this bug is back in php-4.3.1
