PEAR claims php was compiled with old module

Question

I just upgraded to php 5.6.4. When i do pear installs of various packages it complains that if have a module mismatch.

example:

sudo pecl install xdebug
Failed loading /usr/local/php-5.6.4/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so:
/usr/local/php-5.6.4/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so: undefined symbol: zend_execute_ex
Zend OPcache requires Zend Engine API version 220131226.
The Zend Engine API version 220100525 which is installed, is outdated.

PHP Warning:  PHP Startup: PDFlib: Unable to initialize module
Module compiled with module API=20131226
PHP    compiled with module API=20100525

However, 20131226 is php 5.6.4, 20100525 is 5.4 i believe. So oddly pear thinks the modules were compiled w/ 5.6 but the version of php is 5.4. Ive had this the other way around where the module is older than the php version a lot and typically just recompile those module. this one im a bit stumped.

If you still have the old php version lying around, then pear/pecl probably still uses this php version - even if it shows the correct php version in pear version.

Try to change the php_bin pear config setting:

$ pear config-show
..
$ pear config-set php_bin /path/to/new/php
